r - Subset columns in dataframe X based on columns of dataframe Y -


i subset x data frame based in name collumns of y dataframe:

my xdataframe:

ne001   ne002   ne003   1       2       3

my ydataframe:

 ne001  ne003   10      5

my expected output:

ne001   ne003   1       3

any ideas? thank you! ps. subset collumn name, not collumn number.

this it: 

x[,names(x) %in% names(y)]

perhaps want take closer @ r introduction text, see e.g. these r links.
