r - Counting the total number of words in of rows of a dataframe -
i have data frame words in every row. example of rows:

and want count number of each row , write new data frame , have in final csv this:
df,total word,4 word,2 third word,2 word,1

simply use strsplit
split wish , count number of items come out.
df$total <- sapply(df$df, function(x) length(unlist(strsplit(as.character(x), "\\w+"))))
gives me following output:
df total 1 word 4 2 word 2 3 third word 2 4 word 1
