Below is the code I am using but I keep getting an error with the area "stats= "common""

(key.stat <- stby(data = nudging[,c("SCR SCEN", "Groups")], 
                  INDICES = nudging$Groups, 
                  FUN = descr, 
                  stats= "common", 
                  transpose=TRUE, 
                  style = "rmarkdown", 
                  plain.ascii = FALSE))

The error code is:

Error: Can't subset columns that don't exist. x Column common doesn't exist. Run rlang::last_error() to see where the error occurred.

The package is summarytools. The stby code does not work and the error appears at the stats= "common" line. Groups is the IV and is categorical and SCR SCEN the dependent variable and is continuous. Could it be a fault with the data or the Rstudio version?

  • Welcome to Stack Overflow. Please [make this question reproducible](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) by including a small representative dataset in a plain text format and all the relevant code - what library is required for `stby`, for example? – neilfws Jan 19 '22 at 23:39

Not sure why it's not working for you. I tried a similar operation and even made a variable with spaces in the name in the mtcars data and it worked. Does this code work for you?

library(summarytools)
data(mtcars)
mtcars <- mtcars %>% rename("miles per gallon" = mpg)
stby(data = mtcars[,c("miles per gallon", "hp", "cyl")], 
                  INDICES = mtcars$cyl, 
                  FUN = descr, 
                  stats= "common", 
                  transpose=TRUE, 
                  style = "rmarkdown", 
                  plain.ascii = FALSE)

Output

  • Which version of R are you using? – DaveArmstrong Jan 20 '22 at 00:43
  • I am using R-4.1.2. and Rstudio -2021.09.1-372 – Tamara D. Reid Jan 20 '22 at 10:32
  • I think @neilfws was right, for us to help you any further, you need to provide some data that we can use to reproduce the problem. – DaveArmstrong Jan 20 '22 at 12:37
  • Thanks for your help. I started a new R markdown and the problem must be in conflicting libraries. Just using summarytools package gives no error but when I add other packages to carry out other analyses it bring up an error. – Tamara D. Reid Jan 20 '22 at 15:06
