[R] xts objects comparison

2013-11-14 Thread Tstudent
I have the following two xts object:

https://dl.dropboxusercontent.com/u/102669/series1.rdata

https://dl.dropboxusercontent.com/u/102669/series2.rdata

With str i see that they are both xts objects

I can't understand why it's impossible to compare each element.

For example: series1  series2
Why i don't get an xts object with a sequence of true and false?

[R] Load Tawny package on R 2.15.3

2013-11-01 Thread Tstudent


I have R version 2.15.3 When i try to load it:

library (tawny)

i receive this response:

package ‘parser’ could not be loaded

The package Parser in not on Cran anymore, it seems a dead project!
http://cran.r-project.org/web/packages/parser/index.html

If i try to manual install parser_0.1.tar.gz i receive an error and can't
install it.

The question is. Is today impossible to use tawny package? Is there a way to
solve this problem that seems caused by parser package?

Thank you very much

 Install a recent version of tawny that does not depend on the other package?



The most recent version is this:
http://cran.r-project.org/web/packages/tawny/index.html

I can install, but can't load without parser package.
It seems true for 2.15.3 version of R

Someone says that with R 3.0 no problem.

My question is if there is some possibility to have a working tawny on R 2.15.3

I don't want upgrade to R 3.0 because have one package that doesn't work on
R 3.0

 I have no specific expertise here, but I just wanted to point out that
 this sounds like a losing strategy long term: As new packages and
 newer versions of packages come out that fix bugs and add features,
 you'll be unable to use them because you'll be stuck with 2.15.3 . I
 suggest you bite the bullet and follow the experts' advice to get
 things working with the current R version now.
 
 Cheers,
 Bert

It seems that the only possibility for me is to install R 3.0
So i have a question. 
Now i use R 2.15.3 and Rstudio (which is linked to R 2.15.3)
Can i install R 3.0 in another directory but leave R 2.15.3 as default or
primary R  ? Any problems to do this? Something to be careful?
