 Dear all,
 Today I tested a function
 to check R installation
 To this end I uninstalled R
 On installing R again I
 noticed on CRAN today have started
 R 3.4.2
 In gretl preferences I  have found
 that Command to launch R  detected
 the new version but
 Path to R.exe and Path to R library did not
 System: Windows 10
 As the result Start GNU R in menu worked
 but foreign language=R did not (before
 manual corrections) 
As a matter of interest, how do the paths to R.exe and the R library 
differ between R 3.4.2 and your previous version?
In the past I have found these paths unstable and hard to determine.
