Dear R-experts,
How can I remove a certain feature or observation by a part of its name. To be
clear, I have a matrix with 766 observations as a rows. The row names are like
this
70/556
71.1/280
72.1/556
72.1/343
73.1/390
73.1/556
Now I would like to remove all the rows that contain the text 73.1
Any ideas or suggestion please ?
Regards
