Hi,

I must have accidentally deleted my previous post. I am having a really difficult time calculating the LOOCV (leave out cross validation).

table in excel

genes     ALL   AML  p.value
1          1.2     .3      .01
2          .87    .3       .03
3          1.1    .5       .05
4         1.2    .7        .01
5         3.2    1.2      .02
6         1.1    1.1       .5

Do i need to import them into R as a matrix?

Is there any script available where i can calculate the LOOCV?

thanks,
John
