Dear All, Does anyone know if there is any R implementation of the Lempel-Ziv entropy estimator? I searched for it in the entropy contributed package, but unsuccessfully. Cheers Lorenzo

Dear All, I am a bit concerned about the memory consumption of randomForest in caret. This seems to e due to the fact that the option keep.forest=FALSE does not work in caret. Does anybody know a workaround for...

Dear All, I am given some data to analyze. The data is in the form of a Stata database (.dta file). What is the best way to import it into an R dataframe? Is there any particular caveat I should...

Dear All, Please consider the following example library(corrplot) M <- cor(mtcars) corrplot(M, method="circle", type="lower", diag=F) Suppose that I want to have the label "mpg" at the top in black and leave everything else in red...

Dear All, Sorry for the trivial question, but if you are using Linux and want to know the version of your installed libraries, what are you supposed to do? library() just tells you what R libraries you have installed on...

Dear All, I am given a set of files names as: velocity1.txt velocity2.txt and so on. I am sure there must be a way to read them automatically in R. It is really taking me longer to read...

Dear All, I am given some noisy data which (by naked eye) appears to be oscillating first but finally growing. Is there any statistical set (I mean something different from e.g. a linear fit, which would not be convincing...

Dear All, I need to do some very basic R profiling, something along the lines of: run this whole script five times and return the average completion time. I do not want (at this stage) delve into the details of...

Dear All, I can provide a numerical example if needed. My problem is the following: I am using amelia to input some missing data in a dataset. The problem is that some columns consist of integer numbers only and amelia...

Dear All, I hope this is not a FAQ, but my online research was not fruitful. Consider a standard 2D plot generated with the "plot" command. I would like to introduce inside the graph some text with an arrow pointing...

Hi, Probably a trivial question: if you do type something like: out<-nls( here goes the model ), then you can type "out" or "summary(out)" to see the fitted parameters, the quality of the fit etc... but what if you...

Dear All, I am given a time series such at, at every time t_i, I am given a set of data (every element of the set is just an integer number). What I need is an injective function able...

Dear All, I would like to know if anybody is aware of an R implementation of a minimal bounding box ( http://bit.ly/2cKaSgT ) algorithm in R for points in 3 dimensions. It looks like there is no shortage of...

Dear All, I know how to use the boxplot() function to generate a boxplot, but I would like to (automatically) extract 5 numbers (median and the 4 quantiles) for each column and possibly save them into a convenient format. Can...

Dear All, I am starting to use R excellent graphical facilities to produce good-looking plots. However, I do not know yet how for use pedices/apices (e.g. when you write cm^3) and Greek letters (e.g. \sigma...
