Calculate number of characters in string in R

Question

My sample dataset looks like below. I need to calculate the number of characters.

keyword <- c("advertising",
         "advertising budget",
         "marketing plan detail",
         "marketing budget and forecast")

I tried the "nchar" function, but it actually calculates the number of digits. For this sample, the results should be 1,2,3,4.

Perhaps you want to count the number of words, not the number of characters. In any event -- `nchar` doesn't count the number of digits. Your example contains no digits. — John Coleman, Feb 20 '17 at 02:25

One option is str_count and specify the patterns for word (\\w+)

library(stringr)
str_count(keyword, "\\w+")
#[1] 1 2 3 4

Or with base R

lengths(gregexpr("\\w+", keyword))
#[1] 1 2 3 4

unlist( lapply(strsplit(keyword, split = "\ "), length) )
[1] 1 2 3 4
