Hello,
I made a mistake today on simple counting in R, that almost got me into
trouble. After trying multiple times, I finally figured out it's rounding issue
in R.
For exmaple, when I just simply type:
> (6.9-6.3) > 0.6
[1] TRUE
6.9-6.3 should be 0.6 exactly, but R thinks that it's greater

Yes, round(1.5)=2. but round(2.5)=2. I want round(2.5)=3 just like the what
the excel do. Can we change the setting or do some trick so that the
computer will work like what we usually do with respect to rounding.
My system is R 2.8.1, winXP,
. Thanks.

But I want to the answere to be 2 for sure just what we usually do. How can

Ted,
Actually
hi i am creating some variables from same data, but somewhere is different
rouding.
look:
P = abs(fft(d.zlato)/480)^2
hladane= sort(P,decreasing=T)[1:10]/480
pozicia=c(0,0,0,0,0)
for (j in 1:5){ for (i in 2:239){
if (P[i]/480==hladane[2*j-1]){pozicia[j]=i-1}}}
period=479/pozicia
Hi,
you probably want to use ?all.equal instead of ==
I couldn't run your example, though
Hope this helps,
baptiste
