I'm just a beginner, who has just encountered a problem!
1. - I wanted to load a csv file with names in the rows (1st column)
and and numbers in the 2nd til 10th column. The file contains
names in the headers.
- I used; a <- as.matrix(read.table("filename", sep=',",
Question; 1 - I would like to select the first four columns
2 - and execute a pca(plot) from the mva package on
those four columns
3 - how can I set the data type eg(string, integer,
double) separate for each column
Can anyone help me out, Help!
Thanks in advance,
