unique(1:3,nmax=1) freezes R
...length of x is larger than 2 and k=1, and when nmax<length(x)-1 you get error "Error in unique.default(1:5, nmax = 3) : hash table is full".
Of course using nmax=1 doesn't make much sense, but maybe some check would be in place before calling internal unique?

The constant part of the log-likelihood in StructTS
...e constant term, as the likelihood is only
computed for those y which are observed.
This does not affect in estimation of model parameters, but it could have
effects in model comparison or some other cases.
Is there some reason for this kind of constant, or is it just a bug?

CRAN check fails on Solaris, any hints why?
Dear all,
I recently uploaded a new package Rlibeemd to CRAN (http://cran.r-project.org/web/packages/Rlibeemd/index.html, and in github: https://github.com/helske/Rlibeemd), and simple example in help files seems to throw an error on Solaris:
Version: 1.3.1
Check: examples
Result: ERROR
Running examples in ?Rlibeemd-Ex.R? failed
The error most likely occurred in:

There is also illustrative figure in his blog post about the effects of this initial covariance matrix (scroll to the bottom of the page):

R 3.0.0 is released
...ctTS() has a revised additive constant in the loglik
component of the result: the previous definition is returned as
the loglik0 component. However, the help page has always warned
of a lack of comparability of log-likelihoods for non-stationary
models. (Suggested by Jouni Helske.)
o The logic in aggregate.formula() has been revised. It is now
possible to use a formula stored in a variable; previously, it
had to be given explicitly in the function call.
o install.packages() has a new argument quiet to reduce the amount
of output shown.
o Se...

Using valgrind to debug R, extracting column of a mts object causes valgrind to crash
Dear all,
I'm trying to debug my R package with valgrind, but I cannot get past the
point where I load make the data, as valgrind crashes when trying to
extract a single time series object of a multivariate mts object. I'm using
R 2.15.0 with platform x86_64-redhat-linux-gnu (64-bit).
The valgrind.R contains code
data(Seatbelts)
y<-Seatbelts[,"VanKilled"]
And I run
