Dear List, I've created a two-dimensional array which shall contain a value and its error, respectively. These two values are concatenated in al list and bear the names "sl" and "sl_err"
But I can't adress them using the $-notation. a<- array(list(NULL),dim=c(2,2)) a[[1,1]]<- c(a=2,b=3) a[[1,1]]$a ## Fehler in a[[1, 1]]$a : $ operator is invalid for atomic vectors a[[1,1]]["a"] # This works however. ## a ## 2 I always thought these two methods of indexing are equal? Is there any way to use the $-Style indexing?
