Dear R mailing list readers,
I am facing the following problem; for simplicity imagine I am working on a
data frame of, say, 5 columns. The first column is a list of European
countries, the other four are an index (continuous variable) of climate change
impact under 4 different scenarios.
...
However, when I try to use the code as above, R automatically re-order the x-axis
(country) in alphabetical order. This was not unexpected, but I have spent the day
(unsuccessfully) looking for a way to simply tell R not to do that and to keep the
variable "country" as it is now ordered in the data frame to construct the
x-axis of my plot. Is there any way to force it to keep the order as it is in the data
frame ?
Hi Arnaud,
If you want a non-alphabetic ordering of factors, you will have to
explicitly specify the order:
country<-factor(
c("Austria","Belgium","Bulgaria","Czech Republic","United Kingdom"),
levels=c("Austria","Belgium","United Kingdom","Bulgaria",
"Czech Republic"))
