[R] If loop

[Steven Yen]

Thanks. Hmm. The loop is doing what it is supposed to do.

 > try1<-function(joint12=FALSE,marg1=FALSE,marg2=FALSE,
+                cond12=FALSE,cond21=FALSE){
+ # ***************************************************
+ # Testing if loop
+ # ***************************************************
+ if(joint12){
+   {print ("joint12"); cat(joint12,"\n")}
+   {print ("marg1"); cat(marg1,"\n")}
+ } else if (marg1) {
+   {print ("marg1"); cat(marg1,"\n")}
+   {print ("joint12"); cat(joint12)}
+ } else if (marg2) {
+   {print ("marg2"); cat(marg2)}
+ } else if (cond12) {
+   {print ("cond12"); cat(cond12)}
+ } else {
+   {print ("cond21"); cat(cond21)}
+ }}
 > try1(joint12=TRUE)
[1] "joint12"
TRUE
[1] "marg1"
FALSE
 > try1(marg1=TRUE)
[1] "marg1"
TRUE
[1] "joint12"
FALSE
 > try1(marg2=TRUE)
[1] "marg2"
TRUE
 > try1(cond12=TRUE)
[1] "cond12"
TRUE
 > try1(cond21=TRUE)
[1] "cond21"
TRUE
