gtools R package

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, permutations),
• 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)
