Esteemed UseRs and DevelopeRs, Just coming to terms with the very attractive proportional venn gernator, venneuler(), but would like to customize a few things. Is it possible to- -suppress all circle labels? -suppress only certain circle labels? -print specific text...

Esteemed useRs and developeRs, I need to create a '3D line plot' (proper name?) of which an excellent example can be viewed here: http://cococubed.asu.edu/images/87a/images/unknown_pleasures.jpg I have some experience using the rgl...

Hi Cheng, Check out the keep() function in package:gdata. And to be sure the "removed" objects are really removed from system memory i think you need to run gc(). hth, Karl On 8/23/2010 9:00 PM, Cheng...

Hi Mandy and esteemed R users, I'm searching for the functions you used to produce the shaded bounding box (and axis for that matter) of the plot image* attached to your orginal post. Would you or anyone else be...

Esteemed R user's, I'm struggling to achieve some details of a heatmap using heatmap.2(): 1. Change label locations, for both rows & columns from the default right & bottom, to left and top. Can this be done within heatmap...

Esteemed R users and developers, How does one 'programatically' list or call objects for use in a function? For example, i thought i could do something better than this: save(A.cwb, B.cwb, C.cwb, D.cwb, E.cwb...

Hi Dimtris and esteemed useRs, I don't understand why i get this error message when attempting to use merge() - > temp <- merge(x, y[,17, drop=FALSE], by=rownames, sort=FALSE) Error in as.vector(x, mode) : cannot coerce type...

Dear UseRs and DevelopeRs It would be helpful to see the color palette available in the venneuler() function. The relevant par of ?venneuler states: "colors: colors of the circles as values between 0 and 1" -which explains color specification, but...

Thank you Erik! That works nicely now. The file size in (in kilobytes) is equal to the "File>Save As>PDF" method. Still curious why the file sizes (in Kb), differ by a factor of ~2 between the two methods...

Esteemed UseRs and DevelopeRs, Apologies if this question belongs else where, but it does concern R's package installation/maintenance. How does one start R within Emacs/ESS with root privileges? I tried without success: > M-x sudo R Why...

Esteemed UseRs, This must be embarrassingly trivial to achieve with e.g., melt() and cast(): deduplicating records ("pw.X" in example) for a given set of responses ("cond.Y" in example). Hopefully the runnable example shows clearly what i have...

Cheers Greg, That's really simple. That's excellent. Thank you. Sincere thanks for the education. The more i learn, the more i like getting it done with R. karl On 6/28/2010 7:32 PM, Greg Snow wrote...

Esteemed R-users, heatmap.2() is yielding an inappropriate key based on my colors and break-points. In the reproducible example below, the key is inappropriate (to me) because- 1. 'Orange' is simply not represented in the key, despite its...

Esteemed UseRs, I've got many biggish data frames which need a lot subsetting, like in this example: # example eg <- data.frame(A = rnorm(10), B = rnorm(10), C = rnorm(10), D = rnorm(10)) egsub <- eg[eg$A < 0 & eg...

Dear List, I'd really appreciate tip's or code demonstrating how i can achieve some common axis labels integrated into a multiple plot. In my example (below), i'm trying to achieve: -a single "Results 1 (Int)" centered & btwn...

Hi Shira, Check out "venneuler" http://cran.r-project.org/web/packages/venneuler/index.html Labelling can be a little tricky, but if you search this forum for "venneuler" you'll find some tips which helped me. hth, karl On...

Hi Jeff, Subset is indeed what's reuqired here. But using it every time it's needed was generating excessive amounts of obtuse code. So for the sake of clarity and convenience i wanted a wrapper function to replace these...

My problem is that using "[" every time i want to extract my data of interest is cumbersome and verbose for the next guy suffering through reading my code. Since my extractions are always on the same columns and depend on...

Dear R Users, I employed the phyper() function to estimate the likelihood that the number of genes overlapping between 2 different lists of genes is due to chance. This appears to work appropriately. Now i want to try this with...

Cheers Duncan, for your FAST answers and patience. (fast patience?!) I was close. But closer reading of ?save would also have worked i see now :$. LETTERS[] = :) thanks again, Karl On 9/11/2010 2:10 PM, Duncan Murdoch wrote: > On...
