Full_Name: Frank Wagner Version: R 2.1.1 OS: Windows Submission from: (NULL) (193.174.73.34) Hi, The pdf file R-intro descripe on page 27 that lists can be extended by adding numbers. Unfortunately, it's not working ## example : # if i did not declare the variable an error occurs : object not found mylist <- list() mylist[1] <- list(value1=3, value2=5) ## Error
NO! 1. No, this is not a bug! 2. No, this was not an error but a *warning* which tells you that the length does not match. Each Element of *vector* mylist must be a list of length one, hence you cannot assign one of length two. Instead you can say: mylist[1:2] <- list(value1=3, value2=5) This is a question that might go to R-help, if you do not understand what is described in the docs. The manual is correct, hence this is not a bug. Please read the docs on how to post bugs and how a bug is defined ... Uwe Ligges
Can you please help me Thank you Regards Frank Wagner
