conduct pairwise column comparisons without comparing a column to itself
# Hello
# I have a question regarding pairwise calculations of a matrix using a
"for-loop."
# Below I have a matrix "X" with 8 columns. These are genotypic data so
Column1 & Column2 is
# a unit, Column3 & Column4 is a unit, Column5 & Column6 is a unit, and
Coulmn7 & 8 is a unit.
# I have a loop designed to calculate the number of times an individual in

Chinese, Japanese, Korean Tokenizer.
Hi,
I am looking for Chinese Japanese and Korean tokenizer that could can
be use to tokenize terms for CJK languages. I am not very familiar
with these languages however I think that these languages contains one
or more words in one symbol which it make more difficult to tokenize
into searchable terms.
Lucene has CJK Tokenizer ... and I am looking around if there is some
open source that we

Keys used to sign releases
I see that some, but not all, releases provide a local link to the key used
to generate the signature files, which makes it difficult for a script to
use them to verify the signatures.
Gcc solves this problem by including the following on their mirrors page (
https://gcc.gnu.org/mirrors.html):
The archives there will be signed by one of the following GnuPG keys:

How to multiply all dataframe rows by another dataframe's columns
Hello,
I have two data frames, X and Y, with two columns each and different numbers
of rows.
# creation of data frame X
Loc1.alleles <- c(1,5,6,7,8)
Loc1.Freq <- c(0.35, 0.15, 0.05, 0.10, 0.35)
Loc1 <- cbind( Loc1.alleles,Loc1.Freq)
X <- data.frame(Loc1)
#creation of data frame Y
Loc2.alleles <- c(1,4,6,8)

create data frame(s) from a list with different numbers of rows
# Hello,
# I have a list with 6 categories and with different numbers of rows.
# I would like to change each of them into a unique data frame in order to
match
# values with other data frames and perform some calculations.
# Or I could make each category or list element have the same number of rows
and create one large data.frame.
