Hello, I run into a problem:
> ftable(table(Fire, Standard, StoAll), col.vars=c("Fire","Standard")) Error in table(Fire, Standard, StoAll) : object 'Fire' not found I do not understand that because when I read the table everything seems correct. > Stocking_all<-read.table("P://Benchmark//analysis//r//stocking_10//stock ing_all.csv",header=TRUE,sep=",") > names(Stocking_all) [1] "ID_basic_tallesttree" "FID_plot" "Fire" [4] "Time_Fire" "Standard" "Fire_Standard" [7] "ESR" "Fire_Stand" "StoARS2000" [10] "StoWAS2008" "StoAll" And I also get a summary for the variables. I have no clue and would very much appreciate your help.
