Dear R users, I have a dataframe which consists of variables of type numeric and factor. What is the easiest way to split up the dataframe to two dataframe which contain all variables of the type numeric resp. factors? Thank you very much for your efforts in advance! Best, Martin

Dear all, I would like to convert the first column of a dataframe to a date (original format: year (4 digits) and month (last 2 digits)) >str(dat_FF) 'data.frame': 1022 obs. of 4 variables: $ date : int 192607 192608 192609 192610 192611 192612 192701 192702 192703 192704 ... $ Rm.Rf: num 2.69 2.52 0 -3.06 2.42 2.66 0 4.29 0.51 0.57 ... $ SMB : num -2.49 -1.25 -1.38 -0.2 -0.34

Dear all, I would like to ask, if there is a way to make the variance / dispersion parameter $\theta$ (referring to MASS, 4th edition, p. 206) in the function glm.nb dependent on the data, e.g. $1/ \theta = exp(x \beta)$ and to estimate the parameter vector $\beta$ additionally. If this is not possible with glm.nb, is there another function / package which might do that? Thank you very much for

Hello everyone, using the VGAM package and the following code library(VGAM) bp1 <- vglm(cbind(daten$anzahl_b, daten$deckung_b) ~ ., binom2.rho, data=daten1) summary(bp1) coef(bp1, matrix=TRUE) produced this error message: error in object$coefficients : $ operator not defined for this S4 class I am bit confused because some day ago this error message did not show up and

Dear all, I have a matrix X which consists of 2 columns. I would like to convert this matrix into a list where every entry of the list consists of a single row of the matrix. Does anyone have a suggestions how to manage this? Thank you for your efforts in advance! Best, Martin [[alternative HTML version deleted]]

Hello, currently I am estimating an ordered probit model with the function polr (MASS package). Is there a simple way to obtain values for the prediction of the index function ($X*\hat{\beta}$)? (E..g. in the GLM function there is the linear.prediction value for this purpose). If not, is there another function / package where this feature is implemented? Thank you very much for

While it's real handy to have "ControlMaster auto" to have multiple sessions get muxed into one, sometimes it's really helpful to _not_ use the same session (e.g. if you want to ssh -2fNR). It'd be quite nice if there were a flag to tell openssh to not mux the new connection at all - i.e. what "ssh -o ControlPath=none" does. (The 'obvious' invocation `ssh

Dear all, I am trying to use Rcpp to write some files in C++ for use in R. Below is an example for a cpp-file (crossp.cpp). Then I use >sourceCpp("crossp.cpp") in R and the corresponding function is availabe in R. Now I have to question related to this worklfow: 1) Is there a way to see the source file of the "final" cpp-file? (I mean is it possible to see how the
