file="C:/glob.csv"
glob=read.csv(file,header=T)

y=glob$Temperature


z=max(y[1:40])
#  this has a probability of exceedance of 1/41 
# now you can check how this does in the 2nd sample - 
sum=0
for i = 41:100 if (z>y[i]sum=sum+1
sum
sum=sum/60
	sum


error: the loop i=41:100 does not work correctly, only if information after
"if"
is enclosed in parentheses

That's not how you specify a for loop in R. Please read up on the
syntax, e.g. in "An Introduction to R"

It is not a bug in R that your program does not work correctly. Please
do not abuse the bug report system like that.
