dfround.RdFunction to round the numeric variables in a data frame.
dfround(x, digits, drop0=TRUE)a data frame.
either a single integer or a numeric vector of the same length as there are columns in x.
logical (or a vector thereof) to specify whether trailing zeros after the decimal mark should be removed (the default is TRUE).
A simple convenience function to round the numeric variables in a data frame, possibly to different numbers of digits. Hence, digits can either be a single integer (which will then be used to round all numeric variables to the specified number of digits) or a numeric vector (of the same length as there are columns in x) to specify the number of digits to which each variable should be rounded.
Non-numeric variables are skipped. If digits is a vector, some arbitrary value (or NA) can be specified for those variables.
Note: When drop0=FALSE, then formatC is used to format the numbers, which turns them into character variables.
Returns the data frame with variables rounded as specified.
