[R] how to identify values from a column of a dataframe, and insert them in other data.frame with the corresponding id?

[John Kane]

Hi Nerea,

For some reason your post is badl garbled and close to imposible to read.  
Perhaps you need to check your text encoding?

Also to send sample data it is better to use the dput() command.
Do dput(myfile) and then paste the results into your email

Sorry not to be of more help.
