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
