Hi R-experts

I have many text files to read and combined them into one into R that are
output from other programs. My textfile have unbalanced number of rows for
example:

;this is example
; r help
Var1     Var2      Var3      Var4      Var5
0             0.05     0.01        12
1             0.04     0.06        18        A
2             0.05     0.08        14
3             0.01     0.06        15       B
4             0.05     0.07        14       C

and so on
Inames<-as.data.frame(read.table("CLG1mpd.asc",header=T,comment=";"))
Inames<-as.matrix(read.table("example.txt",header=T,comment=";"))
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,
:
  line 1 did not have 5 elements


In bestcase scenerio, I want to fill the blank space with NA's, with matrix
or dataframe
 Var1     Var2      Var3      Var4      Var5
0             0.05     0.01        12        NA
1             0.04     0.06        18        A
2             0.05     0.08        14       NA
3             0.01     0.06        15       B
4             0.05     0.07        14       C

The minimum would be to  remove the column Var5, so that my data.frame would
look like the follows:
 Var1     Var2      Var3      Var4
0             0.05     0.01        12
1             0.04     0.06        18
2             0.05     0.08        14
3             0.01     0.06        15
4             0.05     0.07        14
