[Solved] My dataframe i changing when dropping observations conditionaly

by


This is a very basic use of subset.

data |> subset(ex != 0 | is.na(ex))

Output:

#>    ex
#> 1   2
#> 2   2
#> 3  NA
#> 4  NA
#> 6   1
#> 8  NA
#> 9   2
#> 10  3

PS – create reproducible example

data <- structure(list(ex = c(2, 2, NA, NA, 0, 1, 0, NA, 2, 3)),
                  class = "data.frame", row.names = c(NA, -10L))

data
#>    ex
#> 1   2
#> 2   2
#> 3  NA
#> 4  NA
#> 5   0
#> 6   1
#> 7   0
#> 8  NA
#> 9   2
#> 10  3
