skimr: How to customize Data Summary in skim() output?

Question

I want to use the function skim from R package skimr to produce summary statistics of multiple datasets. To save space, I need to prioritize information that gets displayed. I would like to remove these rows from the Data Summary section of skim output: "Name", "Column type frequency", and "Group variables". Is there an easy way to do this?

I tried skim(iris) and got the following:

-- Data Summary ------------------------
                           Values
Name                       iris  
Number of rows             150   
Number of columns          5     
_______________________          
Column type frequency:           
  factor                   1     
  numeric                  4     
________________________         
Group variables            None  

-- Variable type: factor -----------------------------------------------------------------------------------------------------------------------------------------------------

Instead, I want to display the following:

-- Data Summary ------------------------
                           Values 
Number of rows             150

1 Species               0             1 FALSE          3 set: 50, ver: 50, vir: 50

Answer 1

Function skim returns an object of S3 class "skim_df" sub-classing classes "tbl_df", "tbl", "data.frame" and a print method for that class exists. This print method has an argument include_summary that can be set to FALSE to skip the printing of that information.

s <- skimr::skim(iris)
class(s)
#> [1] "skim_df"    "tbl_df"     "tbl"        "data.frame"

To answer the question, just run

print(s, include_summary = FALSE)
