Dear R helpers, I have one trivial problem while writing an output file in csv format.
I have two dataframes say df1 and df2 which I am reading from two different csv files. df1 has column names as date, r1, r2, r3 while the dataframe df2 has column names as date, 1w, 2w. (the dates in both the date frames are identical also no of elements in each column are equal say = 10). I merge these dataframes as df_new = merge(df1, df2, by = "date", all = T) So my new data frame has columns as date, r1, r2, r3, 1w, 2w However, if I try to write this new dataframe as a csv file as write.csv(data.frame(df_new), 'df_new.csv', row.names = FALSE) The file gets written, but when I open the csv file, the column names displayed are as date, r1, r2, r3, X1w, X2w My original output file has about 200 columns so it is not possible to write column names individually. Also, I can't change the column names since I am receiving these files from external source and need to maintain the column names.
