Hello,
There is a typo, the end colon is missing.
grepl(x, '[^[:alpha:]]')
Hope this helps,

Use pattern "[^[:alpha]]" with grepl.

?grepl
gives you a logical vector for indexing.

Hello All,
I can’t find the answer for this so I thought I would ask you lovely
people.
I have a data frame with a column of names, some of which have
non-alphabetical letters.
How, do I extract the row indexes which do not meat the criteria of
alphabetical [[:alpha:]].
Thanks in advance
All the best
Graeme
library(dplyr)
my_df <- data.frame(name1 = c("david", "mo", "ma4tilda856", "steph",
"hadley", "574383"),
name2 = c("craig", "salah", "dahl", "paris",
"wick",
"turing"), sex = c("m", "m", "f", "f", "m", "m”))
my_df %>%
mutate_all(as.character)
