Dear R help I have conducted a fa() analysis, and I want to use fa.diagram to assess the extent to which the 11 latent factors predict the 37 items in a psychological battery. However, the display on the screen has very large font size for the coefficients of the relationship between the 11 factors and the 37 items, so the numbers overlap and are therefore illegible. When I output this to a

Hi I have used fa() to perform a factor analysis of a psychological battery which is thought to have 11 factors. I can identify which factors the loadings relate to easily enough because I can see which items are loading onto each of the columns in the $loading output. However, how can I identify which items or loadings are being used to create each of the columns in the $scores output? I have

Apologies for continuing to ask about this but . . in my quest to fit a gamma GLMM model to my data (see partial copy of thread below), I'm exploring using hglm today. The question of the day has to do with the errors I'm currently getting from the hglm package. Can hglm handle a model with nested random effects? I don't see an example of one of those in the package documentation. If

Dear r helpers; I'm interested in reading from and writing to large .xlsx files fairly regularly. (Why, the naysayers may ask - and the answer is basically colleagues and clients who prefer that format). I've tried out the XLConnect and xlsx libraries, but the java implementation they use just takes too much RAM for the files I'm working with. gdata leverages perl and works really

Dear R users, I'm starting to use 'apply' functions rather than for loops in R, and sometimes the output is a bit different than what I want. In this case, the command was tapply(myvector,myindex,cumsum) And the output was something like this: $`SNRL1 Core 120` [1] 2.8546 4.0778 5.2983 6.3863 7.5141 8.5498 9.5839 10.6933 $`SNRL1 Core 230` [1] 7.6810 8.7648 9.8382

Hi folks, I'm dealing with a dataset with a lot of NAs, and want to use subset on the data without removing the NAs from the the dataframe; e.g. rws50 <- subset(rw.fire.RW,shigo.av<50) This removes instances with NA for the value in addition to anything <50. Any suggestions much appreciated. *Ben Caldwell* [[alternative HTML version deleted]]

Dear helpers, Does anyone have information on the status of bigmemory and R3.0? Will it just take time for the devs to re-code for the new environment? Or is there an alternative for this new version? Thanks Ben Caldwell [[alternative HTML version deleted]]

Can someone verify that using fw as a filter in iproute2-2.6.11-050330 is broken. Doesn''t seem to work in any case and I saw an earlier post that would lead me to believe this is the case. If so does anyone have a temporary fix? Thanks, Troy

Evening folks, I'm trying to print a series of graphs to .jpeg using a variable as the title, but run into the difficultly that I can't find a way to append the file extension to the .jpeg (in this case extensionless!) files. Example: ---- species.name="CussoniaHolstii" dia<-10:100 biomass = -21.4863 + 0.5797 * (dia ^ 2) biomass jpeg(species.name) plot (biomass,

I have some elements in a vector with extraneous information (e.g. file name and sample IDs) that I'd like to strip from every element. For example, I would like "SPI1.S1.str1.P3.sample.tif" "SPI1.S1.STR2.P1.sample.tif" to read "SPI1.S1.str1.P3" "SPI1.S1.STR2.P1". Will someone help me with the syntax in gsub? It needs to be something like

Dear R help, I've what I think is a fairly simple parallel problem, and am getting bogged down in documentation and packages for much more complex situations. I have a big matrix (30^5,5]. I have a function that will act on each row of that matrix sequentially and output the 'best' result from the whole matrix (it compares the result from each row to the last and keeps the

Hello, In days past, all I had to do was create /etc/xen/auto and put a symlink in there to the config file for each VM I wanted to have started automatically. Since updating to 4.6, this doesn't work.? Period. I'm having a hard time finding what needs to change in order to get VMs to auto start on reboot of a server.? Can someone please point me to documentation that I have missed

Dear r-help, Somewhere in my innocuous function to rotate an object in Cartesian space I've created a monster that completely locks up my computer (requires a hard reset every time).

The script only does this when the input matrix is large, and so my initial
