Dear R-team,

I have written this code for calculation my data file. But there shows 'subscript out of bounds?.
+     dataodd <- data[-(1:18),]
+     dataodd <- dataodd[seq(1,nrow(dataodd), 2),]
+     hitsodd <- table(factor(dataodd[,5]), factor(dataodd[,15]))[2,2]
+     missesodd <- table(factor(dataodd[,5]), factor(dataodd[,15]))[2,1]
+     crejectionsodd <- table(factor(dataodd[,5]), factor(dataodd[,15]))[1,2]
+     falsealarmodd <- table(factor(dataodd[,5]), factor(dataodd[,15]))[1,1]
+     return(coordinationodd <- data.frame(hitsodd, missesodd,crejectionsodd, falsealarmodd))
+ }
Error in table(factor(dataodd[, 5]), factor(dataodd[, 15]))[2, 2] : 
  subscript out of bounds
Error in Reduce(rbind, coordinationodd) : 
  object 'coordinationodd' not found


Could you please tell me how I can fix this problem?

Best,

You don't provide a reproducible example - what does your data look like?

If this were my problem, I would start by working through the function
step by step with one of my files

data <- filelist[[1]]

dataodd <- data[-(1:18),]
and so on, examining the result at every step with tools like dim() and str()
until I found the problem.

There are more fully-developed debugging tools available, but for such
a short function I wouldn't bother.

Include the levels argument in your calls to factor so the tables
all have the same dimensions.
TRUE
  FALSE    2
  TRUE     2
levels=c(FALSE,TRUE) ))

        FALSE TRUE
  FALSE     0    2
  TRUE      0    2

Trying to extract row 2, column 2 from the former will give a subscript-out-
of-bounds error.
