Have you looked here:

I would think your choice depends strongly on the arena of application.
Of course I like BH^2, but that was because I was taught by them.
Hello!
Could someone recommend a good book on Design of Experiments for a Master's
in Data Analytics, please?
I use Montgomery's book for my undergrad course, but was thinking about
something a little more advanced for this one.
Any help much appreciated, particularly with R-related texts.

Perhaps https://cran.r-project.org/web/packages/bcrypt/index.html
might be of assistance.
If not, drop a note back to the list as it'll be trivial to expand on
that to give you an R alternative to Perl.

I have a file containing encrypted contents. The contents can be decrypted
using perl, like this:
open (FILEHANDLE, "/path/to/file")
chomp ($ciphertext = );
use Crypt::CBC;
$cipher = Crypt::CBC->new( -key=> 'my secret key',

You have non-numeric data somewhere in that column, and factor is already a
numeric type (Read about factors in the Introduction to R document that comes
with R). Try
DF$prec_new = as.numeric(as.character (DF$precip)
and then look at
DF$precip[ is.na( DF$precip_new ) ]
to see which values ar

Hello,
Try
as.numeric(as.character(DF$precip))
Hope this helps,

I'm wondering why the values changed when I try to transform factors into

For example, for a data frame DF, there is one column called precipitation,

Using log1p instead of log improves the accuracy of the 'subtract xmax'
algorithm when the largest x is very close to zero. Perhaps that is what
is missing in the Rf_logspace_add.

Hi,

Opinion only (and therefore ignorable):
Unless you have a lot (?) of data, fitting such a model successfully
is likely to be very challenging. I suggest that you consult a local
statistical expert to see if you might take a different approach.

I need a function for R software which computes a mixture of Negative

I found on another site the following function "mixnbinom". It works very
well, but it computes a mixture of only two components:

Thanks for your reply! We are definitely not seeking for help with the

I wanted to make a ggplot2 using Rmpfr high precision data - but cannot

b <- mpfr(2,120)
