Dear all
I have to combine 3D netCDF files (lon, lat, time). The files contain data of
one month and I need a year file containing all the data. Because the
attributes of all files are the same, I copied the first file and appended the
data of the other months. This went well until the provider
Hi there
Thanks for your answers. I didn't expect that this would be so complex.
Honestly, I don't understand everything you wrote since I'm not an IT
specialist. But I read something that reading *.rds files is faster than
loading *.Rdata and I wanted to proof that for my system and R version.
Hi Bill
Thanks for your answer and the explanations. I tried to use garbage collection
but I'm still not satisfied with the result. Maybe the question was not stated
clear enough. I want to test the speed of reading/loading of data into R when a
'fresh' R session is started (or even after a new
Dear all
I was thinking about efficient reading data into R and tried several ways to
test if load(file.Rdata) or readRDS(file.rds) is faster. The files file.Rdata
and file.rds contain the same data, the first created with save(d, '
file.Rdata', compress=F) and the second with saveRDS(d, ' file
Dear Dave
Thanks a lot for your answer. I agree that it is more an R issue than a package
issue. But it's the first time I encountered such a problem.
For my R version (v3.4.1) on x86_64-w64-mingw32 the second part of your answer
only holds for data_temp2; if I do any manipulation to data_temp2
Dear all
I'm a newbie regarding netcdf data. Today I realized that I maybe do not
understand some basics of the netcdf. I want to create a *.nc file containing
three variables for Switzerland. All data outside of the country are NAs. The
third variable is calculated from the first two variables
Hi Marc
That's a workaround I can use. Thanks. I'm a newbie regarding netCDF data. Is
there any information I'm losing when switching between the packages?

Dear Marc
Thanks for your remark. I don't want to use both packages. I mentioned the
package RNetCDF to show that there is a similar function I' d like to use.

Dear all
For a model I need to combine several netCDF files into one (which works fine).
For better overview I'd like to delete/remove some of the attributes. Is there
a simple way doing this?
I'm using the package netcdf4, which creates an object of class(nc) = "ncdf4".
It seems that for earl
Thanks a lot for the fast answer. Sys.setenv(TZ="GMT") is a good solution for
me.
Best regards
