Colleagues,

I attempted to copy data from the clipboard and use rcompanion's
transformTukey command in an attempt to normalize the dataset.

data = read.delim("clipboard")

head(data)
  Flatness
1    7e-04
2    1e-03
3    8e-04
4    5e-04
5    5e-04
6    5e-04

All data are greater than 0.
Data set is heavily right skewed
Error in is.infinite(TRANS) : 
  default method not implemented for type 'list'

Why is this occurring?

What type of value does read.delim return? Use str() to find out.

            

      
      
      
    

        
What type of value does transformTukey expect in the "x" argument? See
help(transformTukey).

Most likely, your "data" is a data.frame, and transformTukey() expects a
vector, requiring you to extract the "Flatness" component from the
data.frame using the `[` or the `$` operator.

Thanks Ivan!

This makes perfect sense now!

All the best,
