Function to round the numeric variables in a data frame.

dfround(x, digits)

Arguments

x

a data frame.

digits

either a single integer or a numeric vector of the same length as there are columns in x.

Details

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.

Value

Returns the data frame with variables rounded as specified.
