Hi All,
I am a beginner in programming in r and please do forgive me if my question
seems to be silly and sometimes not understandable.
1. we have a list of elements in a list say:
ls<-list("N","E","E","N","P","E","M","Q","E","M")
2. We have an another list of tables in a list say:
n <- list("M", "N","E","P","Q","M","N","E","Q","N")
tb <- lapply(1:10, function(i)matrix(sample(4), 2, 2,
dimnames=list(n[sample(10,2)], n[sample(2,2)])))
3. we need to extract values from the table in the list where colname is
always "M" , wherein the rowname should be the 1st element in the list ls
for table 1 in the list tb and 2nd element in table 2 and so on...
for ex:
M N
N 4 1
P 3 2
In table 1 , we need to extract value 4.
Thanks to all in advance.
