[R] ifelse

[HBaize]

Also, to further clarify. When you source or batch file R scripts, objects
are only printed to the screen if you use a print function. That is why the
result of the ifelse does not appear. 

Your original example would have shown the expected result of the ifelse if
it had read: 

print(ifelse ( ddd>360, ddd-360, ddd ) 

adding the print function to the ifelse in your first example, executed
using source(), will give you this output: 

[1] "numeric"
[1] 461 213 238 249 251
[1] 101 213 238 249 251
[1] 461 213 238 249 251
