Arguments

x	a character vector with text
pattern	a text pattern which might be contained in x
...	other arguments, passed on to gregexpr

Value

an integer vector of the same length as x indicating how many times the pattern is occurring in x

Examples

x <- c("abracadabra", "ababcdab", NA)
txt_count(x, pattern = "ab")
txt_count(x, pattern = "AB", ignore.case = TRUE)
txt_count(x, pattern = "AB", ignore.case = FALSE)
