Hi Josh, thanks for your help. I tried so many different things that I am not exactly sure what it was that made it work. I installed the latest version of R and then I could install the latest version of TTR as well. Haky On Tue, Apr 28, 2009 at 7:41 PM, Josh Ulrich <josh.m.ulrich at gmail.com> wrote:
That's odd. ?Does your mirror have the updated Mac binary? You can use install.packages() to install from your local disk. ?See the Examples in ?install.packages.

I see... Thanks. But when I install TTR using install.packages, I get version 0.14. I downloaded the new version in my hard drive but I'm not sure how to install from local drive. I am using MacOs. Do you know how to do this on a Mac? Thanks Haky On Tue, Apr 28, 2009 at 7:08 PM, Josh Ulrich <josh.m.ulrich at gmail.com> wrote:
Haky, It appears you're not using TTR_0.2. ?You should not have this issue with the newest version. Best, Josh -- http://quantemplation.blogspot.com http://www.fosstrading.com On Tue, Apr 28, 2009 at 6:46 PM, Hae Kyung Im <haky.im at gmail.com> wrote:

Hi Josh, I am attaching the following files test.Rdata (with data.xmin, the xts object) replic.r replic.output.txt (output when I source replic.r) Thanks Haky On Tue, Apr 28, 2009 at 5:49 PM, Josh Ulrich <josh.m.ulrich at gmail.com> wrote:
Hi Haky, Could you provide more information? ?I cannot replicate your results.

Hi, for some reason when I calculate RSI on a xts object of length n, I get a result of length n+1 as in the following example:
dim(data.60min)
[1] 23 ?5
class(data.xmin)
[1] "xts" "zoo"
length(RSI(data.60min[,"Close"]))
[1] 24 If I plug in a vector of length 23, RSI gives me a vector of length 23.
length(RSI(runif(23)))
[1] 23 am I missing something here? Thanks Haky -------------------------------------------- Here is the data for your reference:
