how to save the output of a loop

Question

i'm making a for loop to creates and modifiy dataframes, and now i want to save them to my computer. I've tried with differents functions, but either way they don't save or just the last one is saved ( i have 66df). I'm new to R so maybe I'm missing something

my code looks like this

assign(paste0('output_df',sep = '_', i),df)
  
  write_csv(output_df, file = '/output/data frame.csv')

does the assign(past0 change something ? do you have any idea what's wrong ?

Because your output filename is the same. Read about paste. Try something like file = paste0("/output/dataframe_", i, ".csv") — zx8754

The name of the data frame can remain the same, it is the name of the file that should be changed.

By the time it gets to write_csv(), the value of output_df should be different each time, but the name output_df can (and normally would) remain the same. And then you can save it with a different file name each time:

write_csv(output_df, file = paste0("/output/dataframe_", i, ".csv"))
