data |
A dataframe |
condition |
A condition required to be TRUE to set NA. Here, the condition
is specified with a formula, following the syntax: |
dat_ms <- tibble::tribble(~x, ~y, ~z,
1, "A", -100,
3, "N/A", -99,
NA, NA, -98,
-99, "E", -101,
-98, "F", -1)
dat_ms
#replace all instances of -99 with NA
replace_with_na_all(data = dat_ms,
condition = ~.x == -99)
# replace all instances of -99 or -98, or "N/A" with NA
replace_with_na_all(dat_ms,
condition = ~.x %in% c(-99, -98, "N/A"))
# replace all instances of common na strings
replace_with_na_all(dat_ms,
condition = ~.x %in% common_na_strings)
# where works with functions
replace_with_na_all(airquality, ~ sqrt(.x) < 5)
