I am having difficulty installing the package "lattice".
First I tried downloading it from the CRAN site (in the normal way) :
the message said it worked but when I typed library I got an error

Write/Display AR query as Grouped Results?
I''ve got a publications table that contains an author_id foreign key and
a pubrole_id foreign key. What I want to do is query the DB using AR so
that I can get a list of all publications that belong_to a particular
author, and group the results by the pubrole.role_name (Author, Joint
Author, Editor, etc.) so that the results look something like:
Author
book1 info
book2 info
etc.

Good day!
I have a problem in reading Excel files in R and appending them to each other. Suppose we have several Excel files in a directory with headers and want to use R to append them in a single file with an additional variable in the final file indicating from which files the data come from.

almost lower triangular matrices
I have output from a program which produces a distance matrix I want to
read into a clustering program in R.
The output is a .txt file and is 'almost' lower triangular in the sense

So for example a 4-by-4 distance matrix appears as,
1
2 3
4 5 6
i.e. it looks like a lower triangular of a 3-by3.

How to convert blanks to NA
Hi R-helpers,
I have imported data from Excel using the following code:

Excel file also being empty (blank) in the resulting dataframe.
I am not used to having blanks (rather NAs) and I think these are
caused by the colClasses argument.

RODBC: forcing a special column to be read in as character
