tklistbox selection

I'm posting yet another question about tcltk since I'm still struggling
with the package. I'm trying to create a tklistbox and a ttkcombobox on
the same parent and am having a problem. Here's an example:
library(tcltk)
tt <- tktoplevel()

Problem with intersection between two different tables
Hi,
I'm a beginner with R.
I have two different tables with
the variable name dmr1 and tp2 a given following. v1 is the common column field of
the both tables. In the first table column v3 is always v2+1 while in
the second table v2 and v3 hold the range. I want to know which rows
of tb1 intersect with the range between v2 and v3 of tb3. I need some one's kind help to solve this

Dear colleagues,
I'd like to reshape a datafame in a long format to a wide format, but
I do not quite get what I want. Here is an example of the data I've
have (dat):

Cross-tabulations next to each other
I have the following relatively simple problem. Say we have three
factors, and we want to create a cross-tabulation against each of the
other two:
x <- factor(rbinom(5, 1, 1/2))
y <- factor(rbinom(5, 1, 1/2))
z <- factor(rbinom(5, 1, 1/2))
table(x,y)
table(x,z)
This looks like:
y
x 0 1
0 2 0
1 1 2
z
x 0 1
0 1 1

getting the by() function to work properly
Hola everyone,
Solving this issue would be a huge time saver for analyzing my thesis data, so I'll try to be as concise as possible and hope that someone can give me a hand.
I am trying to run a function that I created, which works fine until I try to use it with the by function. That function is listed at the bottom (f3) just in case that might be the issue. Essentially I have compiled a

lmer binomial model overestimating data?
Hi folks,
Warning: I don't know if the result I am getting makes sense, so this
may be a statistics question.
The fitted values from my binomial lmer mixed model seem to
consistently overestimate the cell means, and I don't know why. I
assume I am doing something stupid.
Below I include code, and a binary image of the data is available at

split & rbind (cast) dataframe
Hi,
I would like to split dataframe based on one colum and want
to connect the two dataframes by rows (like rbind). Here a small example:
# The orgininal dataframe
df1 <- data.frame(col1 = c("A","A","B","B"),col2 = c(1:4), col3 = c(1:4))
# The datafame how it could look like
df2 <- data.frame(A.col2 = c(1,2), A.col3 = c(1,2), B.col2 = c(3,4),

not enough charcters available in %J or confusing blanks?

I try to create PDF files with an modified script from Buchan Milne and

Because it is better for the users to find an file with an similar name

Handling large data sets via scan()
I'm trying to read in datasets with roughly 150,000 rows and 600
features. I wrote a function using scan() to read it in (I have a 4GB
linux machine) and it works like a charm. Unfortunately, converting the
scanned list into a datafame using as.data.frame() causes the memory
usage to explode (it can go from 300MB for the scanned list to 1.4GB for
a data.frame of 30000 rows) and it fails

how can I convert a long to wide matrix?
Hi Jim,
Thank you very much for your suggestions. I used it but it gave me three
sites. But actually I do have only two sites "Id_X" and "Id_y" . In fact
"A" is repeated two times for "Id_X". If it is repeated, I would like to
take the first one among many repeated values.

Capability problems dovecot 2.0
Hi,
I had some problems connecting TB 2.x with dovecot 2.0. TB2 complained about not being an IMAP4 server. TB 3 worked.
It seems that dovecot 2.0 doesn't return capabilities when queried. Maybe some wrong config, thoug?
Here are the debug logs from TB2 comparing dovecot 2.0 (not working) and dovecot 1.2 (working):

how can I convert a long to wide matrix?
Hi Marna,
I think this is due to having three rows for id_X and only two for
id_Y. The function creates a data frame with enough columns to hold
the greatest number of values for each ID variable. Notice that the
SITE_n columns contain three values for id_X (A, A, B) and two for
id_Y (A, B, NA) as there was no third occasion of measurement for the
latter. Even though there are only two _values_
