Tu file "plantula.txt" no esta aqui (I think).

In short: you are passing some function the name of a file that  
doesn't exist. Try passing the absolute path to the plantula.txt file  
to your call to ``file()``

I've got no clue what you say apart from the warning message. But the 
message suggests that there is "No such file or directory". Use 
list.files() to see which files are in your current working directory. 
Use setwd() to change to the correct working directory, which is 
probably the problem.

cheers,
Paul
