Dear All.,
I've created R-code for which a user will be asked to choose between 2
analyses. I've written one function for each type of analysis. Within
each function, the users is prompted to enter information. An example
is:
cat("Enter value for lower Linf :\n")
L1<-scan(n=1)
cat("Enter value for upper Linf :\n")
L2<-scan(n=1)
cat("Enter Linf interval :\n")
int_L<-scan(n=1)
cat("Enter value for lower K :\n")
K1<-scan(n=1)
cat("Enter value for upper K :\n")
K2<-scan(n=1)
cat("Enter K interval :\n")
int_K<-scan(n=1)
I thought I could evaluate and run the appropriate function at the end
of the program by:
if(event==1) explore() else evaluate()
If I run the whole program and either explore() or evaluate() is run,
the first four prompted entries are skipped over. The console output
for event==1 is TRUE looks like:
> if(event==1) explore() else evaluate()
Enter value for lower Linf :
1:
Read 0 items
Enter value for upper Linf :
1:
Read 0 items
Enter Linf interval :
1:
Read 0 items
Enter value for lower K :
1:
Read 0 items
Enter value for upper K :
1:
I then tried another way. I created
runcase<-ifelse(event==1,"explore","evaluate")
At the bottom of the program I used:
eval(call(x=runcase))
But I still get the same problem.
Any suggestions?
Thanks for your help
