Dear R-experts,

I still have problems with the reading of a matrix.

Input: matrixData6.txt

A-Paar B-Paar C-Paar D-Paar E-Paar
A 1 3 5 7 9
B 2 4 6 8 10

R-commands:
y=read.table(file="Z:/Software/R-Programme/matrixData6.txt") y

Result:
  A.Paar B.Paar C.Paar D.Paar E.Paar

A      1      3      5      7      9
B      2      4      6      8     10


If you look into the txt-file you can recognize that the column names are not the same. Why?

If I add in the txt-file the line "MyData:" infront of all followed by a newline. The R-command as above response an error. How can I read the modified input and get the following result:

MyData:

   A.Paar B.Paar C.Paar D.Paar E.Paar

A      1      3      5      7      9
B      2      4      6      8     10

Another stupid question might be hows can I change the column and row names after I made "read.table"? I want to have the following result, for example:

MyData:

       G      H      I      J      K
M      1      3      5      7      9
N      2      4      6      8     10

I studied all manuals I could find and the help but could not understand the examples or interpret it right for my case.

Thanks for help,

Corinna
