Dear community, I am desperately seeking a savor floundering in a pitfall for a few days. ? I have used BFG Repo-Cleaner for deleting files over 5mb in the git history. (Thanks to a recommendation from the community!) However, BioChecker...

Hi! I have a dissimilarity matrix X and try to compare it with X' = dist(cmdscsale(X,k)). If I increase k, I should expect that the error (or fit) should monotonically decrease, right. Here is a sample code; library...

R Help Feel sure there is a simple answer to this but answer has eluded me so far. NB. Using R 2.6.0. I am plotting a simple chart using plot(): plot(df, ylim=c(as.numeric(min(df...

Dear R users: I am having difficulty to place x-axis location alternatively top/bottom side in Lattice plot, which is composed of seven-column as following: E1 E2 E3 E4 E5 E6 E7 Case1 -505.85 -75.32 494...

Hi, I am attempting to create a new raster based on values of another raster. In the Arc world, this is called a "conditional statement" or "con statement". I am having quite a bit of difficulty figuring this out in...

Hi there, I would like to find a more efficient way of permuting the rows and columns of a symmetrical matrix that represents ecological or actual distances between objects in space. The permutation is of the type used in a...

Hi, I'm wondering why the spectrum() phase of quadrature couple isn't purely +/-pi. But mostly, I'm looking for a recommended way to take a 2-D spectrum and convert it into a single complex array. Kindly consider...

Thank you. Changing the function argument limit to 20 variables resolves the error. If this limit can be relaxed, that would be helpful for future development. Thank you for Rcpp, and your patience with my ill-formed posts. JP On...

Hi all, I have a problem of Rf_initEmbeddedR function. I've tried with: try { int Argc1 = 1; char *Argv1[] = {"Rtest_1"}; int Argc2 = 1; char *Argv2[] = {"Rtest_2"}; // Init R(first) Rf_initEmbeddedR(Argc1, Argv1); // R package load SEXP...

Dear R users, I want to find the latent factors from a kind of time-series data describing temporal changes of concentration using a factor analysis technique called 'factor analysis of dynamic structure (FADS).' I learned how to form the...

Hello I am a private investor and have been wondering about the feasibility of building my own personal piece of software to help with my investing. In particular, I am thinking of a desktop application that has the following features...

Dear Sir/Madam: I simply want to draw x-y plot with Julian dates (x) and numbers (y). Please see below for my program. In the older version of R, the plot(jdat, miles) worked without any problem. But, with...

Hello, I am trying to create a virtual environment in the zzz.r file of my package, and my package is currently passing on Windows and failing on Debian with 1 ERROR. This is the ERROR: * installing *source* package ?PytrendsLongitudinalR...

Ah, yes... I see it now in Writing R Extensions.? Apologies for the oversight. Regarding rmarkdown, is it redundant to include rmarkdown in VignetteBuilder if it is in Suggests, or is perhaps needed in the build config as a separate...

Thanks David. I used the wtd.quantile in Hmisc. Works great and is easy for a newbie like me. I am attempting to send the quantile values to boxplot, and it works for the most part. My problem is that...

Thanks you! I should have realized that without explicitly engaging some form of averaging (which raises a windowing question) that the coh is always 1. On 7/12/2011 4:48 AM, Rolf Turner wrote: On 12/07/11 09...

Thanks for your comment. Beside axis location, I have another question for you. If I wanted to change the matrix column names shown on the lattice plot, which argument should be used to handle it? (I'd like to know...

Thanks Martin. What i'm hoping to do is have a class object, with a member method that can change values of slots in the object, without having to assign values by external assignment to the object. Something like this...
