Hi everyone,
I am a newbie in R and in this discussion list. I am trying to use R package
"ncdf" to read values of temperature from a NCDF file. I did it before to
another file using the function "get.var.ncdf", but now there is an error
that I can not solve, and I would really appreciate if you could help me.
I am using R version 2.11.1 (2010-05-31) in a machine with Linux
2.6.26-2-amd64.
> library(ncdf)
> file_temp<-open.ncdf("File.nc")
> temp<-get.var.ncdf(file_temp,"tasmax",verbose=TRUE)

Thank you very much for your attention!
