Hi dear list, If anybody could help me, it would be great! I have two files: File 1 is a list (one column and around 100000 rows) File 2 is a list with all the names from file one and a few more (one column and more than 100000 rows) What I want is to add a column in file 2 that says which name appeared in file 1 and which doesn't (yes and no would work as a code) It's very important to

Hi, I'm new in the mailing list but I would appreciate if you could help me with this: I have a big matrix from where I need to delete specific rows. The second entry on these rows to delete should match any string within a list (other file with just one column). Thank you so much! Laura

Hi all, I'd appreciate if anyone can help me with this... I have a data frame that looks like this: 1 + name1 1 2 3 2 + name2 5 9 10 2 - name3 56 74 93 1 - name4 65 75 98 I need to rearrange this in a way so that the rows with "1" in the first column, and "-" in the second column; then columns 4 and 6 should switch places. That is, column 6 would be now column 4 and

Hello, I don't know if the result of acos(0.5) == pi/3 is a bug or not. It looks strange to me. Inaki Murillo

Dear members, I am performing multivariate analysis on marine benthic populations using R. At first glance I found ca and VEGANO packages to be the suitable for the task, but neither has incorporated Detrended Canonical Correspondence Analysis (DCCA), which is just the method I want to apply on my data. I've looked for alternative packages containing the method, but my suspicion is that

Greetings to all -- I am having a silly problem that I just can't solve. Someone has given me an .RData file will hundreds of data frames. Each data frame has a column named ResultValue, currently character when it should be numeric. I want to loop through all of the data frames to change the variable to numeric, but I cannot figure out how to do it. My best guess was along the lines of:

Dear list, I have a data frame where one of the columns are p values with scientific notation mixed with regular numbers with decimals. >a=data frame >a P OR N 0.50 0.7500 237 0.047 1.1030 237 0.124 0.7742 237 0.124 0.7742 237 0.0080 1.1590 237 0.50 0.7500 237 4.5e-07 1.2 237 5.6e-04 0.9 237 when I try to do >pval=a$P/2 R gives me an error saying "In Ops.factor(pval, 2)

This may be an FAQ, but a (perfunctory) search failed to turn it up. Suppose I have a function foo(...){<something>} and I want to obtain, inside foo, the names of items comprising the ``...''. E.g. if I call foo(melvin,clyde,irving) I want to be able to loop through the ``...'' and successively obtain the text strings "melvin", "clyde", and

I recently upgraded both of my samba servers (mirrors of each other) to 3.0.4, my log files now fill with the following messages (hundred lines per day): Jun 24 13:55:33 Clyde smbd[8597]: [2004/06/24 13:55:33, 0] lib/util_str.c:safe_strcpy_fn(602) Jun 24 13:55:33 Clyde smbd[8597]: ERROR: string overflow by 1 (9 - 8) in safe_strcpy [LIBRA~V$.DOC] Jun 24 14:20:34 Clyde smbd[8597]: [2004/06/24

I have vague recollections of seeing this question discussed on r-help previously, but I can't find the relevant postings. I want to determine (from within a given function) the name of the function calling that given function. E.g. if I have a function foo() which calls a function bar(), and also a function clyde() which calls bar(), I want to have, in the code of bar(), an instruction

Hi I have a long data set on which I want to do Bland-Altman style plots for each rhythm type Using ggplot2, when I use geom_hline with facet_grid I get an extra set of empty panels. I can't get it to do it with the "Diamonds" data supplied with the package so here is a (much abbreviated) example: > lvexs cvd_basestudy ecd_rhythm fixed_time variable_time 1 CBP05J02

Hi R experts, I'm using the xyplot function in lattice to draw a multipanel plot consiting of 5x6 scatterplots. Now I need to link single points in each of those scatterplots (=panel),but the points, that need linking are different for each panel. I tried to use the panel.segments function for that, but I can't address each panel separately. Links right for panel 1, show up in all other

Hi With ggplot2 I can very easily create beautiful histograms but I would like to put two histograms on the same plot. The histograms may be over-lapping. When they are overlapping the bars are shown on top of each other (so that the overall height is the sum of the two). Is there any way to get them to display overlapping (with smaller value in front, larger value behind) so that the overall
