ICYMI: stringr 1.6.0 🧵
This update brings performance gains and new fns for string manipulation in #RStats.
Highlights include: Faster replacements with `str_replace_all()`, 🐫 new case tools to camel, snake, and kebab, case-sensitive str_like(), & more.

Had not realized that R (>=4.0, per StackOverflow) provides selective function loading. Nice way to avoid naming conflicts.
Instead of barfing a package's entire namespace into your environment when you don't need to:
library(stringr, include.only = c("str_extract", "str_remove"))

Just learned: It's so easy to sort strings that are numbers in proper numerical order with the {stringr} #Rstats 📦's `str_sort()` function and numeric = TRUE!!
x <- c("8", "10", "1", "40")
str_sort(x, numeric = TRUE)
[1] "1" "8" "10" "40"
x <- c("8", "10", "1", "40")
str_sort(x, numeric = TRUE)
[1] "1" "8" "10" "40"

For today's project, I'm having to do a bit of copy-pasting of text from a PDF to add information to a quarto website. Which brings me back to one of my favourite #rstats tricks, and possibly my favourite function name! stringr::str_squish()
![Code snipped showing the tidy up of two sentences which are initially very broken up by line breaks and extra spaces, using stringr::str_squish().
# One of my favourite R tricks when copying from a PDF - because we all have to do that at some point!
stringr::str_squish(
"Here's some text that
has come from a
pdf and,
slightly irritatingly, has
lots of linebreaks that it would
take ages to delete one by one. Oh and also
the odd extra space.")

One of these days I'm going to submit a PR to {stringr} with the function:
unfuck_excel()
It takes strings like "May-23" and converts them back into "05-23" because I'm tired of my street numbers being destroyed #rstats

I think {stringr} is my favorite basic utilities package.
Ever need to count the number of characters in a variable (sometimes based on a pattern)? The #rstats {stringr} package is great for that. ✨

![d12
# A tibble: 4 x 2
id item1
<dbl> <chr>
1 1 "c,a,p"
2 2 "a,p"
3 3 ""
4 4 "p"
Same as above, item1 represents student responses of a word. Each letter represents a correct phonetic sound. We want to count the number of correct sounds for each student. However, this time, our data has commas between letters so we cannot use stringr::str_length() because it will count the commas, giving us incorrect scores.
Instead we use stringr::str_count() and add the argument pattern = and we add the regex pattern “[a-z]” which says to count any lowercase letter a to z.
d12 %>%
dplyr::mutate(item1_score = stringr::str_count(item1, pattern = "[a-z]"))
# A tibble: 4 x 3
id item1 item1_score
<dbl> <chr> <int>
1 1 "c,a,p" 3
2 2 "a,p" 2
3 3 "" 0
