[R] Sub-setting a data frame by partial column names?

[barah]

Hi Sarah,

Thanks a lot for the suggestion. It is working for me. 
subsetData<- bigData[,grep(partialName, colnames(bigData))]


But if i want to extract multiple columns along with the columns with
similar names, how do i that? Say the others column have similar values for
all the columns with similar partialnames. I tried the following

subsetData<- bigData[,grep("partialName", "Colname1", "Colname2",
colnames(bigData))]

It did not work.
Do you have any suggestion ?

Regards,

Pankaj Barah
