Sorry for the emails. I just checked and the problem is still there. Is there a proper way to reformat the decimal places, such as three or four decimal places? Thanks.
If maintain four decimal places, the numbers are: 1.2000, 1.3100, 1.4000, etc. On Thu, Jan 5, 2017 at 10:46 PM, lily li <chocol...@gmail.com> wrote: > I found that the last column is the digits 2.00, so the problem is solved. > > On Thu, Jan 5, 2017 at 10:42 PM, lily li <chocol...@gmail.com> wrote: > >> Hi R users, >> >> I'm trying to concatenate two strings, while each string has numbers. >> For example, strings1 = c(1.2, 1.31, 1.4, 1.51, etc), strings2= c(2.1, >> 2.22, 2.3, 2.44, etc).
