Dear R list members, I have a question regarding xyplot. I managed to make a xyplot of all the IDs by using the syntax below:
xyplot(PA ~ CRPC + CRPT | ID, data = redinteract) Now, I'd like to make a graph of a specific ID number (e.g., only ID number 301). I thought I could use "subset", but it seems to be not working. Could anyone let me know how I can make a graph of a specific ID? Thank you for your help in advance!
