Simple question:
Why doesn't the following work? Or what 'R' rule am I missing?
tclass <- "Testing 1 2 3"
if(tclass == "Testing 1 2 3")
{
cat("Testing", tclass, "\n")
}
else
{
cat(tclass, "\n")
}
I get an error 'else' is unexpected.
The segment
if(tclass == "Testing 1 2 3")
{
cat("Testing", tclass, "\n")
}
Is syntactically complete, so that when the parser comes to the
``else'' it
finds it ``dangling'' and hence ``unexpected''.
The following wee adjustment works:
tclass <- "Testing 1 2 3"
if(tclass == "Testing 1 2 3")
{
cat("Testing", tclass, "\n")
} else {
cat(tclass, "\n")
}
cheers,
