| db_bin {dbplot} | R Documentation |
Uses the rlang package to build the formula needed to create the bins of a numeric variable in an unevaluated fashion. This way, the formula can be then passed inside a dplyr verb.
db_bin(var, bins = 30, binwidth = NULL)
var |
Variable name or formula |
bins |
Number of bins. Defaults to 30. |
binwidth |
Single value that sets the side of the bins, it overrides bins |
library(dplyr)
# Important: Always name the field and
# prefix the function with `!!`` (See Details)
# Uses the default 30 bins
mtcars %>%
group_by(x = !! db_bin(mpg)) %>%
tally()
# Uses binwidth which overrides bins
mtcars %>%
group_by(x = !! db_bin(mpg, binwidth = 10)) %>%
tally()
