I’m happy to present some info about the latest version of

cgwtools, my collection of handy “toys” which make everyday work in R a bit easier. Enjoy!

The newly added functions include:

base2base – Function to convert any base to any other base (up to 36).

binit — Create histogram bins for each unique value in a sample. That is, automatically use the unique values as bin ranges, rather than dividing up the overall range by some factor.

cumfun — Function calculate the cumulative result of any function along an input vector.

maxn , minn — Functions to find the n-th maximum or minimum of a vector or array.

which.maxn , which.minn — Functions to find locations of the n-th maximum or minimum of a vector or array.

polyInt — Function to find intersection points of two polygons.

segSegInt — Function to find intersection point between two line segments (NOT lines).

Other functions previously provided:

approxeq — Do “fuzzy” equality and return a logical vector (rather than a single status as all.equal does).

dim — Function to return dimensions of arguments, or lengths if dim==NULL.

findpat — Function to locate patterns ( sequences of strings or numerical values) in data vectors.

popd , pushd — Performs equivalent of ‘bash’ command with same name

getstack — Returns the current directory stack that pushd and popd manipulate

dirdir — Wrapper function around dir() which returns only directories found in the specified location(s).

lsclass, lssize, lstype — list all objects with the specified class, size, type .

lsdata — List all objects in an ‘.Rdata’ file.

maxRow, maxCol, minRow, MinCol — Functions which mimic ‘max.col’ to find minimum or maximum of rows or columns.

mystat — Calculate and display basic statistics (max, min, mean, median, std dev, skew, kurtosis) for an object.

resave — Add some objects to an existing ‘.Rdata’ – type file.

seqle — Extends ‘rle’ to find and encode linear sequences.

inverse.seqle — Inverse of ‘seqle’
