Re: [R] montly mean temp plot

THe problem is that when you read the data in, 'month' was converted to a factor. Try the following to get it converted to a factor, but in the order you want for processing: x <- read.table(yourFile, ..., as.is=TRUE, na.strings="DNA") # prevent conversion to factor x$month <- factor(x$month, le

Re: [R] montly mean temp plot

Without a reproducible example (we don't have month and X1999) it is hard to tell for sure, but my guess is that month is an (unordered) factor without the ordering specified, so it defaults to alphabetic. Change it to a factor with the months properly ordered and the plot should match what you
