The gtools R package provides functions to assist in R programming, including:
- assist in developing, updating, and maintaining R and R packages (
ask, checkRVersion, getDependencies, keywords, scat),
- calculate the logit and inverse logit transformations (
logit, inv.logit),
- test if a value is missing, empty or contains only NA and NULL values (
invalid),
- manipulate R’s .Last function (
addLast),
- define macros (
defmacro),
- detect odd and even integers (
odd, even),
- convert strings containing non-ASCII characters (like single quotes) to plain ASCII (
ASCIIfy),
- perform a binary search (
binsearch),
- sort strings containing both numeric and character components (
mixedsort),
- create a factor variable from the quantiles of a continuous variable (
quantcut),
- enumerate permutations and combinations (
combinations, permutation),
- calculate and convert between fold-change and log-ratio (
foldchange, logratio2foldchange, foldchange2logratio),
- calculate probabilities and generate random numbers from Dirichlet distributions (
rdirichlet, ddirichlet),
- apply a function over adjacent subsets of a vector (
running),
- modify the TCP_NODELAY (
de-Nagle) flag for socket objects,
- efficient
rbind of data frames, even if the column names dont match (smartbind`),
- generate significance stars from p-values (
stars.pval),
- convert characters to/from ASCII codes (
asc, chr),
- convert character vector to ASCII representation (
ASCIIfy).
- apply title capitalization rules to a character vector (
capwords)
