Hi,
is it possible to format real (double) numbers in a data frame to an
exact format?
I need something like format(..., digits=5) but this is a suggestion
only and I need exactly 5 digits. Example where there are more than 5
digits printed follows.
I can do it via
cbind(as.numeric(sprintf("%.5f",column_1)),
as.numeric(sprintf("%.5f",column_2)),...)
but it is really annoying and there must be an easier solution.
