That rather depends on what kind of plot you want to use.
Here is one option that you can use without any changes:
######
con <- textConnection("
Months Prec
1 Jan 102.1
2 Feb 69.7
3 Mar 44.7
4 Apr 32.1
5 May 24.0
6 Jun 18.7
7 Jul 14.0
8 Aug 20.0
9 Sep 32.4
10 Oct 58.9
11 Nov 94.5
12 Dec 108.2
")
tab <- read.table(con)
closeAllConnections()
rm(con)
with(tab, barplot(Prec, names = as.character(Months)))
#####
## If you want to adjust the factor so that the levels remain in natural months
order, then
#####
tab <- within(tab,
Months <- factor(Months, levels = month.abb))
with(tab, barplot(Prec, names = levels(Months)))
######

Hello;
How do I plot these data in R without the Months being ordered alphabetically?
Months Prec
