I am using xtable in knitr to create tables and currently I left align all xtable columns because it is easy and repeatable.
However, I am wondering if there is a way to align the xtable columns depending on the type of data in the dataframe column (num, chr, int, etc...) so that I can right align numbers and left align characters.
Thanks!
I think it's already the case : from xtable example page
