get_dummies.( .df, cols = c(where(is.character), where(is.factor)), prefix = TRUE, prefix_sep = "_", drop_first = FALSE, dummify_na = TRUE )
.df |
A data.frame or data.table |
cols |
A single column or a vector of unquoted columns to dummify.
Defaults to all character & factor columns using |
prefix |
TRUE/FALSE - If TRUE, a prefix will be added to new column names |
prefix_sep |
Separator for new column names |
drop_first |
TRUE/FALSE - If TRUE, the first dummy column will be dropped |
dummify_na |
TRUE/FALSE - If TRUE, NAs will also get dummy columns |

col1 = c("a", "b", "c", NA),
col2 = as.factor(c("a", "b", NA, "d")),
var1 = rnorm(4,0,1))
