I have so many gz files of the type (filename.nc.gz) where nc stands for netcdf file.
I used the following commands : path="C:/Documents and settings/AER/NorthAmerica-West/zipedfiles/" # examples of zipped files files <- list.files(path, recursive=TRUE, full.names=TRUE) files <- grep(".*\\.gz$", files, value=TRUE) This gave me list of gz files. To unzip (extract it) I used the following command. for (flst in 1:length(files)) { f1<-strsplit(files[flst],"\\.gz") tmp<-sapply(f1, '[[', 1) gunzip(tmp) } But, this does not work. I have also defined an output path as: outpath='c:/temp/' and also used something like this: sapply(files,function(i) gunzip(i,destname=outpath) that also did not work. I am frustrated an anything helps - including if there is any alternative package. Thank you all for your help.
