Simple control structure issue
R is a case-sensitive language: 'if' (lowercase 'i') is a keyword and 'If' (uppercase 'I') is not. Bill Dunlap TIBCO Software wdunlap tibco.com On Fri, Jun 23, 2017 at 1:00 PM, Michael Ashton <

I am having a hard time with 'next'. I come from the "sloppy" school that
learned BASIC with Goto.
Conceptually next seems pretty straightforward. I just can't get it to
work correctly in my code. Here's a stripped down version:
WhichRunNow<-"Daily"
Cnums=c(0,1,"2b3")
Cpers=c("Daily","Daily","Weekly")
for (j in (1:length(Cnums))) {
If (!identical(Cpers[j],WhichRunNow)){
next
}
print(j)
}
So, this should print the number "3", which it does. It prints 3 because
"WhichRunNow" is "Daily", and only for j=3 is Cpers[j] not identical to
"Daily". But R seems very unhappy with how it gets there:
WhichRunNow<-"Daily"
Cnums=c(0,1,"2b3")
Cpers=c("Daily","Daily","Weekly")
for (j in (1:length(Cnums))) {
+ If (!identical(Cpers[j],WhichRunNow)){
Error: unexpected '{' in:
"for (j in (1:length(Cnums))) {
If (!identical(Cpers[j],WhichRunNow)){"
next
Error: no loop for break/next, jumping to top level
}
Error: unexpected '}' in "}"
print(j)
[1] 3
}
Error: unexpected '}' in "}"
Obviously something with my syntax, but I can't see what I'm doing wrong!
