Hello All,
I'm new to R, but I can't account for the results from the simple script
below and it looks simple enough.
Description: When A is generated by seq(), A[A==x] incorrectly returns
numeric(0) for some values of x (in A) but not others.
##########################
A<-seq(0,1,by=.05)
#These return numeric(0), but others in the set return the correct value
A[A==.3]
A[A==.6]
A[A==.7]
A[A==.15]
A[A==.35]
A[A==.85]
A[A==.95] #A[20]
# This works fine
B<-seq(0,1,by=.05)
A[A==B]
# This also works fine
A<-c(0,.05,.1,.15,.2,.25,.30,.35,.40,.45,
.50,.55,.6,.65,.7,.75,.8,.85,.9,.95,1)
A[A==.3]
##########################
R, RGui 2.6.2 (2008-02-08)
Windows XP Professional SP 2
Pentium(R) D CPU 2.80GHz, 2G RAM
Hoping someone else can reproduce it.
Regards,
Eric Set
