...ng a time series for the Mackey-Glass equation: dx/dt = 0.2 x(t-tau)/(1 + x(t-tau)^10) - 0.1 x(t) for the case there tau = 17. I tried the "ddesolve" package but the dde(...) function seems to hang, not producing anything. Can someone show me the R script how to do this? - Mike Beddo [[alternative HTML version deleted]]

Greetings, When I try "install.packages('Rcpp')" it fails when compiling api.cpp (line 39). This is Rcpp 0.11.3. I searched my filesystem, and indeed I do not have execinfo.h anywhere. After some effort, I got R build on AIX. Now I am trying to build the packages I need. Rcpp is crucial. I first build R with the native IBM XL compilers, and Rcpp wouldn't build. That was

Greetings! Can someone provide a simple script for a R function that recursively builds a binary tree. I am most familiar with C and pass by reference, but I think R is like Fortran and pass by value. - Mike Beddo

I'm a newcomer to R. I can't seem to find any documentation how to add error bars to points in scatter plots. I guess I could plot the points, then compute and plot line segments in the X and/or Y directions to represent the errors? - Mike -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

...ocess. I don't know if SQL server can communicate to R through a socket, that's why I think I need an intermediate program. All of this (R, SQL Server) would run on the same Windows server box. Some small code examples for 1) would be helpful, but advice would be better. - Mike Beddo [[alternative HTML version deleted]]

Hi. I need to apply run a regression analysis for groups of data of fixed length:100 As, 100 Bs, 100 Cs etc. eg x Key Value A 1 A 21.2 A 4 A 6.5 ...repeat 96 times with differing values of A B 1 B 2.3 B NA B 6.5 ...repeat 96 times with differing values of B etc I run these against a linear model using tapply(data$Value, data$Key,FUN=regr,100)

Hi, tryCatch seems to be evaluating the all expressions wrapped in it before passing control to the error handling function. For example, the code below will try to evaluate "results" even though the call to odbcConnect fails. I was hoping that the mechanism would work in the same way as a C++ try catch structure and pass control to the catch... as soon as an exception is generated.
