dbWriteTable error message
I am at loss of what is going on here ...
I am trying to write to a SQLite database:
con <- dbConnect(dbDriver("SQLite"), dbname="pres-docs.rqda")
I have a data frame that is 889 rows by 7 columns. The column number
and types agree with the database table columns and column type.

replicate lines of data frame
Greetings!
I am just now learning to use R for my dissertation project. I need
to manipulate a lot of text and numeric data. I created a data frame
that has 7 columns and 127 unique rows. Now I need to replicate each
line 6 times and then later change values in the first 2 columns.
I am trying to figure out how to accomplish this. I think that I need
to use rep(my.df, each=6) but it does

stacked plot
Hi!
I am trying to use ggplot2 to create a stacked bar plot. Previously I
tried using barplot() but gave up because of problems with the
positioning of the legend and other appearance problems. I am now
trying to learn ggplot2 and use it for all the plots that I need to
create for my dissertation.
I am able to create normal bar plots using ggplot2, but I am stomped
with the stacked bar plots.

Works from CLI but not from prompt
Greegings!
Any idea why this works from the command line, but not from a source
file? This is driving me (more) insane.

findAssocs()
I am trying to find the math behind the "tm" package findAssocs()
?findAssocs does not say anything besides "association" and "correlate"
Usually entering "findAssocs" at the CLI gives the code for a R
function, but in this case I obtain:
function (x, term, corlimit)
UseMethod("findAssocs", x)
<environment: namespace:tm>
Any ideas?

Greetings!
I am a new user of R. The only one in my department, all others use SPSS.
I have two data sets of students with test scores, pretest and
posttest. The first column StuNum and then columns of scores.
The problem is that the lists are slightly different not all students
are in both data sets.
So I did:
intersect(pretest$StuNum, posttest$StuNum) -> common.id

KDE panel configuration
I am running CentOS 4.2 with KDE 3.5.1 from kde-redhat.org. I am not
able to configure the panels:
control center -> desktop -> panels
comes up, but is empty. Only the frame and the buttons on the bottom
show. KDE 3.5.1 on Kubuntu does not have that problem.
Has anyone that same problem?

Rails in High School Curriculum?
Hi folks,
I''m working with a local high school in the Portland, OR area on the
subject of computer science curriculum. We are thinking of introducing
a class in web development and I think Rails would be a perfect vehicle.
I''ve done some searching on the web but haven''t found any suggestion of
HS curriculum for Rails. Any pointers or suggestions?

Survey Package with Binary Data (no Standard Errors reported)
Hi,
I'm trying to get standard errors for some of the variables in my data
frame. One of the questions on my survey is whether faculty coordinate
across curriculum to include Arts Education as subject matter. All the
responses are coded in zeros and ones obviously. For some of the other
variables I have a 2 for those that responded with "Don't Know".
I'm getting NA for
