geom_histogram with column data that has a lot of NAs

[JeffF]

I have a large data set large where one of the columns of data contains whole numbers and a goodly number of NAs. How do I create a histogram and ignore the NAs?

NA NA 79 63 60 NA 63 NA 58 NA 57 56 63 50 NA NA NA 60 52 NA NA 57 ...

Thanks,
Jeff

Add na.rm = TRUE to the geom arguments

Hi @JeffF,
In histograms the NAs are ignored by default.
The ggplot() output includes a warning.

x <- c(NA, NA, 79, 63, 60, NA, 63, NA, 58, NA, 57, 
       56, 63, 50, NA, NA, NA, 60, 52, NA, NA, 5)

length(x)
#> [1] 22
length(x[!is.na(x)])
#> [1] 12

# NAs are excluded by default
hist(x)

library(ggplot2)

ggplot() + geom_histogram(aes(x))
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
#> Warning: Removed 10 rows containing non-finite values (`stat_bin()`).
