The base package
base-package The R Base Package
Description
Base R functions Details
This package contains the basic functions which letR function as a language: arithmetic, in- put/output, basic programming support, etc. Its contents are available through inheritance from any environment.
For a complete list of functions, uselibrary(help = "base").
.bincode Bin a Numeric Vector
Description
Bin a numeric vector and return integer codes for the binning.
Usage
.bincode(x, breaks, right = TRUE, include.lowest = FALSE)
Arguments
x a numeric vector which is to be converted to integer codes by binning.
breaks a numeric vector of two or more cut points, sorted in increasing order.
right logical, indicating if the intervals should be closed on the right (and open on the left) or vice versa.
include.lowest logical, indicating if an ‘x[i]’ equal to the lowest (or highest, forright = FALSE)
‘breaks’ value should be included in the first (or last) bin.
3
4 .Device Details
This is a ‘barebones’ version ofcut.default(labels = FALSE)intended for use in other functions which have checked the arguments passed. (Note the different order of the arguments they have in common.)
Unlikecut, thebreaksdo not need to be unique. An input can only fall into a zero-length interval if it is closed at both ends, so only ifinclude.lowest = TRUEand it is the first (or last forright = FALSE) interval.
Value
An integer vector of the same length asxindicating which bin each element falls into (the leftmost bin being bin1).NaNandNAelements ofxare mapped toNAcodes, as are values outside range of breaks.
See Also
cut,tabulate
Examples
## An example with non-unique breaks:
x <- c(0, 0.01, 0.5, 0.99, 1) b <- c(0, 0, 1, 1)
.bincode(x, b, TRUE) .bincode(x, b, FALSE) .bincode(x, b, TRUE, TRUE) .bincode(x, b, FALSE, TRUE)
.Device Lists of Open/Active Graphics Devices
Description
A pairlist of the names of open graphics devices is stored in.Devices. The name of the active device (seedev.cur) is stored in.Device. Both are symbols and so appear in the base namespace.
Value
.Deviceis a length-one character vector.
.Devicesis apairlistof length-one character vectors. The first entry is always"null device", and there are as many entries as the maximal number of graphics devices which have been simul- taneously active. If a device has been removed, its entry will be""until the device number is reused.
Devices may add attributes to the character vector: for example devices which write to a file may record its path in attribute"filepath".
.Machine 5
.Machine Numerical Characteristics of the Machine
Description
.Machineis a variable holding information on the numerical characteristics of the machineRis running on, such as the largest double or integer and the machine’s precision.
Usage .Machine
Details
The algorithm is based on Cody’s (1988) subroutine MACHAR. As all current implementations of Ruse 32-bit integers and use IEC 60559 floating-point (double precision) arithmetic, the"integer"
and"double"related values are the same for almost allRbuilds.
Note that on most platforms smaller positive values than.Machine$double.xmincan occur. On a typicalRplatform the smallest positive double is about5e-324.
Value
A list with components
double.eps the smallest positive floating-point number x such that 1 + x != 1. It equals double.base ^ ulp.digitsif eitherdouble.base is 2 ordouble.rounding is 0; otherwise, it is (double.base ^ double.ulp.digits) / 2. Normally 2.220446e-16.
double.neg.eps a small positive floating-point number x such that 1 - x != 1. It equals double.base ^ double.neg.ulp.digits if double.base is 2 or double.rounding is 0; otherwise, it is (double.base
^ double.neg.ulp.digits) / 2. Normally 1.110223e-16. As double.neg.ulp.digits is bounded below by -(double.digits + 3), double.neg.epsmay not be the smallest number that can alter 1 by subtrac- tion.
double.xmin the smallest non-zero normalized floating-point number, a power of the radix, i.e.,double.base ^ double.min.exp. Normally2.225074e-308.
double.xmax the largest normalized floating-point number. Typically, it is equal to (1 - double.neg.eps) * double.base ^ double.max.exp, but on some machines it is only the second or third largest such number, being too small by 1 or 2 units in the last digit of the significand. Normally1.797693e+308. Note that larger unnormalized numbers can occur.
double.base the radix for the floating-point representation: normally2.
double.digits the number of base digits in the floating-point significand: normally53.
double.rounding
the rounding action, one of 0 if floating-point addition chops;
1 if floating-point addition rounds, but not in the IEEE style;
2 if floating-point addition rounds in the IEEE style;
6 .Machine 3 if floating-point addition chops, and there is partial underflow;
4 if floating-point addition rounds, but not in the IEEE style, and there is partial underflow;
5 if floating-point addition rounds in the IEEE style, and there is partial under- flow.
Normally5.
double.guard the number of guard digits for multiplication with truncating arithmetic. It is 1 if floating-point arithmetic truncates and more thandouble digits base- double.basedigits participate in the post-normalization shift of the floating- point significand in multiplication, and 0 otherwise.
Normally0. double.ulp.digits
the largest negative integerisuch that1 + double.base ^ i != 1, except that it is bounded below by-(double.digits + 3). Normally-52.
double.neg.ulp.digits
the largest negative integerisuch that1 - double.base ^ i != 1, except that it is bounded below by-(double.digits + 3). Normally-53.
double.exponent
the number of bits (decimal places ifdouble.baseis 10) reserved for the repre- sentation of the exponent (including the bias or sign) of a floating-point number.
Normally11.
double.min.exp the largest in magnitude negative integerisuch thatdouble.base ^ iis positive and normalized. Normally-1022.
double.max.exp the smallest positive power ofdouble.basethat overflows. Normally1024. integer.max the largest integer which can be represented. Always231−1 = 2147483647.
sizeof.long the number of bytes in a Clong type: 4 or 8 (most 64-bit systems, but not Windows).
sizeof.longlong
the number of bytes in a Clong longtype. Will be zero if there is no such type, otherwise usually8.
sizeof.longdouble
the number of bytes in a Clong doubletype. Will be zero if there is no such type (or its use was disabled whenRwas built), otherwise possibly12(most 32-bit builds),16(most 64-bit builds) or 8
(CPUs such as ARM where for most compilers long double is identical to double).
sizeof.pointer the number of bytes in a CSEXPtype. Will be4on 32-bit builds and8on 64-bit builds ofR.
longdouble.eps, longdouble.neg.eps, longdouble.digits, ...
introduced inR4.0.0. Whencapabilities("long.double")is true, there are 10 such "longdouble.<kind>"values, specifying thelong double property corresponding to its"double.*"counterpart. See also ‘Note’.
Note
In the (typical) case wherecapabilities("long.double")is true,Ruses thelong doubleC type in quite a few places internally for accumulators in e.g.sum, reading non-integer numeric constants into (binary) double precision numbers, or arithmetic such asx %% y; also,long doublecan be read byreadBin.
For this reason, in that case, .Machine contains ten further components, longdouble.eps,
