Dear all,

i get the following error when reading *.nc4 data:

Error in R_nc_open: No such file or directoryError in
open.ncdf("D:/Ag/rst_1980_prate.nc4") :
  Error in open.ncdf trying to open file D:/Ag/rst_1980_prate.nc4


library("ncdf")
prec <- open.ncdf("D:/Ag/rst_1980_prate.nc4")
lons <- get.var.ncdf(prec,"lon")
lats <- get.var.ncdf(prec,"lat")
