问题
I want to use the function skim from R package skimr on Windows. Unfortunately, in many situations column, hist is printed incorrectly (with many <U+2587>-like symbols), as in the example below.
Question: is there an easy way to either disable column "hist" and prevent it from being printed or prevent it from being calculated at all? Is there an option like hist = FALSE?
capture.output(skimr::skim(iris))

#> [2] " n obs: 150 "
#> [3] " n variables: 5 "
#> [4] ""
#> [5] "-- Variable type:factor ------------------------------------------------------------------------"
#> [6] " variable missing complete n n_unique top_counts"
#> [7] " Species 0 150 150 3 set: 50, ver: 50, vir: 50, NA: 0"

#> [9] " FALSE"

Changing the locale to Chinese (as in this answer) does not solve the problem, but makes it worse:
Sys.setlocale(locale = "Lithuanian")
df <- data.frame(x = 1:5, y = c("Ą", "Č", "Ę", "ū", "ž"))
Sys.setlocale(locale = "Chinese")
capture.output(skimr::skim(df))
#> Error in substr(names(x), 1, options$formats$.levels$max_char) : invalid multibyte string at '<c0>'
回答1:
skim_with(numeric = list(hist = NULL)) This is in the "Using Skimr" vignette.
