Summarize a data.rrame — summarizeDF • miscTools

This function summarizes each variable that is in a data.frame. It can be used, e.g., in an R script to write summary information about a data.frame into a text file that is in a version control system so that one can see in the version control system whether one or more variables in the data frame have changed.

Usage

summarizeDF( dat, printValues = TRUE, maxLevel = 20, file = NULL, ... )

Arguments

dat: a data.frame.
printValues: logical. If FALSE only MD5 checksums are returned, which could be desirable if the data frame contains confidential data that should not be included in the output.
maxLevel: integer. If the number of unique values in a variable is less than or equal to the number specified in this argument (and argument printValues is TRUE), a frequency table is included in the output.
file: a character string or a writable connection naming the file to write to.
...: further arguments forwarded to sink() if argument file is not NULL.
