Re: [R] Pasting data into scan()

I think that Mozilla Thunderbird replaces tabs with blanks routinely. I was actually pasting from Crimson Editor but results are identical with Notepad and MS Word. However there is no problem when pasting from WinEdt:

 > strength <- scan()
1: 0.023 0.032 0.054 0.069 0.081 0.094 7: 0.105 0.127 0.148 0.169 0.188 0.216

13: 0.255   0.277   0.311   0.361   0.376   0.395
19: 0.432   0.463   0.481   0.519   0.529   0.567
25: 0.642   0.674   0.752   0.823   0.887   0.926
31:

Read 30 items

and scanning the file directly works with or without ' sep="\t" ':  > strength <- scan("C:\\Files\\Teaching\\STAT321\\tensile.dat") Read 30 items
 > strength <- scan("C:\\Files\\Teaching\\STAT321\\tensile.dat",sep="\t") Read 30 items

I will send the file to BR (but not to the list!)
