var producing NA

[jcanner]

Hello! In vs 1.9.1 and 1.9.2 on R 4.5.1 and 4.5.2 when var() is run with a missing value it returns NA even though na.rm = TRUE is added. Base R still works though. Other functions perform as expected (mean, sd) when na.rm = TRUE is added
Recreation of Issue

missing <- c(1, 2, 3, 4, NA)
mosiac::var(~missing, na.rm = TRUE)
[1] NA

stats::var(missing, na.rm = TRUE)
[1] 1.666667

Thanks. I'll have to take a look. I don't recall changing anything there recently. Looks like the other functions (mean, median, etc) work as expected. But var() is trickier because stats::var() works differently.

In the meantime, you could usedf_stats() if your data live in a data frame:

> df_stats( ~ x, data = D, var)
Warning message:
Excluding 1 rows due to missing data [df_stats()]. 
  response      var
1        x 1.666667

Looks like I simply didn't pass na.rm along in one place. Should be fixed now.

x <- c(1:4, NA)
mosaic::var(x)
#> [1] NA
mosaic::var(~x)
#> [1] NA
mosaic::var(x, na.rm = TRUE)
#> [1] 1.666667
mosaic::var(~x, na.rm = TRUE)
#> [1] 1.666667
