描述

This may be an issue with R as opposed to skimr, but it always bothers me. I'd appreciate help if you have any. Basically, numbers that should be essentially zero are displayed in scientific notation. Is there some way to avoid this other than the round() function? Here is an example:

library(tibble)
library(dplyr)
library(skimr)
t <- tibble::tibble(
  x = c(7.250, 71.283, 7.925, 53.100, 8.050, 8.458, 51.862, 21.075, 11.133, 30.071)
)
t <- dplyr::mutate(t, 
  x_c = x - mean(x), 
  x_z = x_c / sd(x)
)
skim(t)
#> Skim summary statistics
#>  n obs: 10 
#>  n variables: 3 
#> 
#> -- Variable type:numeric -------------------------------------------------------
#>  variable missing complete  n     mean   sd     p0    p25    p50   p75  p100     hist
#>         x       0       10 10 27.02    23.6   7.25   8.15  16.1  46.41 71.28 ▇▂▂▁▁▃▁▂
#>       x_c       0       10 10 -8.9e-16 23.6 -19.77 -18.87 -10.92 19.39 44.26 ▇▂▂▁▁▃▁▂
#>       x_z       0       10 10 -3.3e-17  1    -0.84  -0.8   -0.46  0.82  1.88 ▇▂▂▁▁▃▁▂

研究方向: Examine how skimr formats numeric values for display. Look at the print and knitr methods in R/print.R and R/knit print.R. Review issue comments for proposed solutions, such as using 'format' with 'scientific = FALSE' or adding an option to control notation.
