Is there a way to vectorize this? [with correction]
** Sorry to repost. I forgot to include a function necessary to make the example work ** I apologize up front for this being a little long. I hope it's understandable. Please let me know if I need to clarify anything. Several months ago I wrote a series of functions to help me take my R analyses and build custom reports in html files. Each function either builds or modifies a string of

Combining plaintext and plotmath expressions
I searched the archives and did not find a solution, so I pose this question to those well-versed in the use of plotmath and expressions. I have a list of strings in an external CSV file which I wish to use sometimes as plot axis labels and sometimes as plot titles. These strings combine plaintext and a few mathematical expressions (Greek letters, subscripts). Moreover, I sometimes need to

regular expressions
Dear list, I have the following text to parse (originating from readLines as some lines have unequal size), st = c("START text1 1 text2 2.3", "whatever intermediate text", "START text1 23.4 text2 3.1415") from which I'd like to extract the lines starting with "START", and group the subsequent fields in a data.frame in this format: text1 text2

plotting labels (not values) on xy plot
I have 2 vectors, x and y and have done an xy plot. I want to plot the label (name?) of the vector on the plot rather than the value. text(x,y, labels = x) gives me the value of x. text(x,y, labels = labels(x)) gives me something like c("text1","text2"..) plotted for each point text(x,y, labels = names(x)) gives nothing print(x) gives me [,1] text1

Converting a matrix to a dataframe: how to prevent conversion to factor
Colleages I am running R 2.1.0 on a Mac (same problem occurs in Linux). In some situations, I have mixed text/numeric data that is stored as characters in a matrix. If I convert this matrix to a dataframe, the numeric data becomes factors, not what I intend. TEXT <- paste("Text", 1:4, sep="") NUMBERS <- 10 + 4:1 MATRIX <- cbind(TEXT,

Fast way to call an R function from C++?
Hi, I'm looking for a most efficient way to call an R function from C++ in a package. I know there are two functions (`R_forceAndCall` and `Rf_eval`) that can do the "call" part, but both are slow compared to calling the same function in R. I also try to use Rcpp and it is the worse one. Here is my test code: C++ code: ``` // [[Rcpp::export]] SEXP C_test1(SEXP f, SEXP x) { SEXP
