I am trying to organise gigantic tables and get kinda stuck.
I have a dataframe such as :
v1 <- c('D7','X',23) v2 <- c('D7','Y',56) v3 <- c('D7','Z',84) v4 <- c('D8','X',11) v5 <- c('D8','Y',12) v6 <- c('D8','Z',35) book <- data.frame(v1,v2,v3,v4,v5,v6)
and I have the uniqued values of column 1:
lvl <- unique(book[,1]) > lvl  "D7" "D8"
I am able to creat a matrix with the levels (D7, D8 here)
I want to add X, Y and Z as columns, and the values in the matching lines.
I guess I'll need to use some homemade functions, but I'll definitly need help to get started.
Thank you so much!
