Hello,
If you want to subset then you must refer to a variable in the original
data set. In your example there is no 'x' in the output of table.
set.seed(2023)
random <- LETTERS[rpois(100, 10)]
(tbl <- table(random))
#> random
#> C D E F G H I J K L M N P Q S
#> 1 2 4 4 8 13 14 10 17 9 11 2 1 3 1
subset(tbl, tbl > 10)
#> random
#> H I K M
#> 13 14 17 11
So it is subsetting vector data as wanted.
It is your expectation that a part of the table should be returned that
is not in agreement with the data you have.
Hope this helps,
