Tidyverse functions that I always forget

tibble::enframe() converts a named vector to a tibble and tibble::deframe() does the opposite
forcats::fct_infreq() reorders a character or factor column in place, and can be used in ggplot:

ggplot(mtcars %>% mutate(carb = as.character(carb)), aes(fct_infreq(carb),fill=carb)) + geom_bar()

stringr::str_detect can be used to search for multiple strings in a vector by using paste collapse:

fruit <- c("apple", "banana", "pear", "pinapple")
mystrings <- c("apple","pear","grape")
str_detect(fruit, paste(mystrings,collapse="|"))

#> [1]  TRUE FALSE  TRUE  TRUE
