what is wrong with for and if cycle in R
3 messages · Jie Tang, Ingmar Visser, Pascal Oettli
I get this error below, there seems to be hidden character in your input instead of a parenthesis:
for(ity in 1:4)
+ {
+ if (ity==1?
Error: unexpected input in:
"{
if (ity==1?"
{
+ print(ity) + } Error in print(ity) : object 'ity' not found
}
Error: unexpected '}' in "}"

hi
I used a two nested cycle by if and for by such code
for(ity in 1:4)
{
if (ity==1?
{
print(ity)
}
}
when I run the code it failed and R tell me that
"error: unrespected '}' in "}""
and when I reduce a }
for(ity in 1:4)
{
if (ity==2?
{
print(ity)
}
R will print 4 but not 2 as what I repect
Could anyone tell me what is the matter with R and how to modify it?
thank you .

Hi, It seems the right prenthesis ")" in the "if" statement is in different encoding.
From your script:
charToRaw('if (ity==1?')[11:13]
[1] ef bc 89
charToRaw(')')
[1] 29 By changing the right parenthesis, it works fine. HTH, Pascal
