Hi Orlando,
This is not a reproducible example because of the line
MyGraphData <- read.graph ( file = "0.edges" , directed = FALSE )
We don't have the file "0.edges" .
But here's an example that reproduces the error message. Maybe it will help
you find your problem.
DF <- data.frame( x=NA, y=5 )
if ( any( DF[1,] != DF[2,]) ) cat("hello world\n")
# Error in if ( any( DF[1,] != DF[2,]) ) cat("hello world\n") :
# missing value where TRUE/FALSE needed
HTH,
Eric
