under tab "file" then select "import dataset" and then "from SPSS" . In the newly opened window in "Browse" find and select your considered SPSS file and then choose " import" .
for saving them in R again under tab "file" select save as or save all.
Samira Ahmadi my problem has solved, file has saved . Once again thank you so so much. It has saved my time. When I was searching I was reading different methods and not a single appropriate one to save the file on R studio. As to do the analysis on R it is necessary that file is saved .
Many professors and students now use Rstudio instead of R , because it is easier to work with. Whatever you want , you can search it on the internet. There are even various websites about using softwares. also YouTube
but , every time you need a help or you have a question about R you can ask me . If I know, I will definitely answer. Good luck
Samira Ahmadi , you state "Many professors and students now use Rstudio instead of R." RStudio is an editor for sending code to the R environment. It can do this in a few ways, and is convenient, but you are running R. There are other R editors, like Tinn-R.
