Hi all, I encountered a problem when trying to read in an Illumina chip annotation file. The offending file is large, so I zipped it up and posted it at http://www.genetics.ucla.edu/labs/horvath/CoexpressionNetwork/tmp/ProbeInfo_Expression.txt.bz2 Executing this: annot = read.table(bzfile("ProbeInfo_Expression.txt.bz2"), comment.char="", sep =

Dear All, I am struggling with the following problem: I am given a NxN symmetric matrix P ( P[i,i]=0, i=1...N and P[i,j]>0 for i!=j) which stands for the relative distances of N points. I would like use it to get the coordinates of the N points in a 2D plane. Of course, the solution is not unique (given one solution, I can translate or rotate all the points by the same amount and generate

Hello, I'm trying to read in a fairly large file into R, and am getting an odd error (65000 rows, 37 columns) Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : line 25628 did not have 37 elements That line DOES have 37 elements. As A test, I tried deleting it, and a few surrounding lines. Same error occurs with a different line number. Is there some hard

I thought some of you might be amused by this. In my non-work time, I'm an avid weaver and teacher of weaving. I'm working on a project involving creating many detailed weaving patterns, so I wrote R code to automate it. Details here: http://stringpage.com/blog/?p=822 If the overlap between R users and avid tablet weavers turns out to be >> 1, I'll polish it up and turn it

Hi, I have a set of x, y points where x represents dates and y actual values. I am trying to plot a line graph of the data with points on top, but R is connecting the wrong points with lines. Does anyone know how I can rectify this. Please see sample below: x= 24/09/2009 09:13 16/10/2009 11:17 24/10/2009 21:43 11/09/2009 18:34 22/08/2009 15:45 10/08/2009 00:30 14/08/2009 14:52 24/09/2009

Hello I have created a graph using the following commands: <<< startBReP3O1T <- diffs$BReP3O1T - diffs$diff_BReP3O1T endBReP3O1T <- diffs$BReP3O1T x <- seq(47,89, length = 10) ymin <- min(min(startBReP3O1T), min(endBReP3O1T)) ymax <- max(max(startBReP3O1T), max(endBReP3O1T)) y <- seq(ymin, ymax, length = 10) plot(x,y, type = 'n', xlab = 'Age', ylab =

Hi Sarah, Thank you for your help. I tried using CR1<-as.matrix(CR1) but gives error Error in corrplot(CR1, method = "circle") : The matrix is not in [-1, 1]!. I am using a corrplot library.

Hi all, How can I set open files that contain values of Zero =0? These are valid values for the parameters I need to evaluate. I have tried CSV and tab formats. Trying XL Connect and/or XLConnectJars dies not seem to work to open Excel files so I am at a loss on how to get the data into a DF. Sample of data with 0 values: Filename Dur TBC Fmax Fmin Fmean Fc S1 Sc Pmc g8221843.13#

Dear list, I was curious how to subtract a vector from matrix? Say, I have mat <- matrix(1:40, nrow=20, ncol=2) x <-c(1,2) I want, x-mat[1,] and x-mat[2,], and so on... Basically, subtract column elements of x against column elements in mat. But x-mat won't do it. Thanks, Mike [[alternative HTML version deleted]]

I am trying to change the inter-line spacing in grid.text(), but I just don't find how to do it. pushViewport(viewport()) grid.text("The inter-line spacing\n is too big") popViewport() Can anyone help? TIA, Mark

I need the output to have groups and the probability any given record in that group then has of being in the response class. Just like my email in the beginning i need the output that looks like if A and if B and if C then %77 it will be D. The examples you provided are just simply not similar. They are different and would take interpretation to get what i need. On Apr 14, 2016 1:26 AM,

I am trying to replicate the SAS proc univariate in R. I got most of the stats I needed for a by grouping in a data frame using: all1 <- ddply(all,"ACT_NAME", summarise, mean=mean(COUNTS), sd=sd(COUNTS), q25=quantile(COUNTS,.25),median=quantile(COUNTS,.50), q75=quantile(COUNTS,.75), q90=quantile(COUNTS,.90), q95=quantile(COUNTS,.95), q99=quantile(COUNTS,.99) )

Hello, I'm new to R and work with psychometrics (Item response theory). I was using a package called "cirt" to model a data that contains only 0s, 1s and 9s. The package is basically used for Monte Carlo Markov Chain estimation of parameters and I specified 5000 iterations. The model seems to run fine but when I try to recover odds ratio statistics using the function

Dear r-Gods! I am interesting in making an equivalent command like outreg in stata where I get all my 8 regressions in one table. Does R have an easy command to that? MVH Dave [[alternative HTML version deleted]]

I have a graph plotted in r.The x axis tickmarks are at 0,5,10. I need a graph with resolution of tickmarks at 0.1 interval.When i place tickmarks of 0.1 intervals using the following command axis(1, at=seq(0,5,0.1), cex.axis=0.7, las=2) I only get the tickmarks of 0.1 interval that are very closed placed in the graph.I need to increase the spacing between each tickmark. Please anyone help out

That does clarify for me that you're missing a step: I didn't clearly follow your description at first. corrplot expects a correlation matrix, not your original data. You need to use cor() first. That's pretty clear in the documentation. See for instance the examples: data(mtcars) M <- cor(mtcars) corrplot(M) Sarah On Sat, Mar 17, 2018 at 12:00 PM Shivi Bhatia <shivipmp82 at

Hi just a quick question in which I must use the "function and return" part of R. If I was asked to define a function called "median" where the function has a single argument x and returns the median value of a vector. How would I go about saying the median = element x in terms of n (say (n + 1)/2 or whatever it would be) if there is an even amount of elements, or x in terms
