r - Set dimnames of a matrix -

I was trying to set the row name of a matrix from the list of names read through csv.read () I am It just sets the row name to "1".

  Labels & lt; -read.csv ('labels.csv', header = f, sep = ';', comment.char = '', as.is = F) labeled V1 V2V3V4V5V6V7V8 V9V10V11V121 Ball 11 Ball 9 Ball 12 Ball 2 Ball 6 Ball 7 Ball 1 Ball 3 Ball 10 Ball 18 Ball 2 Ball 4 Line.Name (M) & LT; -Labals   
 Where M12x12 is the double matrix.  
 This is what I get  
  & gt; Line. Name (M) [1] "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" "1"   
 Any help is appreciated, thanks.   
 
 
 You are probably running into problems because you have data for  factor  s Read in the form    row.names (M) & lt; - sapply (label, as.character)
