While doing some embedded programming and trying to figure out how to generate a hand coded SEXP equivalent of the line "t.test(x,conf.level=(1-p))$conf.int[2]" I had an idea for an addition to the embedded API. There are a number of hidden or static parse functions (R_ParseBuffer, R_Parse1Buffer, etc.) which take an IoBuffer* and returns a parsed tree. If one or more of these

Full_Name: Hsiu-Khuern Tang Version: 2.0.0 OS: Debian GNU/Linux Submission from: (NULL) (156.153.255.236) Hi all, If fit is an rpart object, plot(fit, uniform=TRUE) ignores uniform=TRUE if the graphics device is not already open. To reproduce this: library("rpart") example(plot.rpart) dev.off() # <- works OK without this plot(fit, uniform=TRUE) # <- uniform=TRUE is ignored

Hi, The behavior of ``` SEXP R_ParseVector(SEXP, int, ParseStatus *, SEXP); ``` defined in `src/include/R_ext/Parse.h` appears to be inconsistent depending on the string to be parsed. Trying to parse a string such as `"list(''=1+"` sets the `ParseStatus` to incomplete parsing error but trying to parse `"list(''=123"` will result in R sending a message to the

Full_Name: Hsiu-Khuern Tang Version: 1.3.0 OS: GNU/Linux (Debian unstable) Submission from: (NULL) (192.6.19.124) Hi all, I am not sure this is a bug rather than an intentional design, but here goes: If I do > a <- matrix(1:4, nrow=2) > dimnames(a)[[1]] <- c("a", "b") I get the following error message because dimnames(a) is NULL: Error: more elements

Dear List, When I try to parse code containing newline characters with R_ParseVector, I get a compilation error. How can I compile code that includes comments and newlines? I am using the following: void* my_compile(char *code) { SEXP cmdSexp, cmdExpr = R_NilValue; ParseStatus status; PROTECT (cmdSexp = allocVector (STRSXP, 1)); SET_STRING_ELT (cmdSexp, 0, mkChar (code));

Hi again, Beside R_ParseVector()'s possible inconsistent behavior, R's handling of zero-length named elements does not seem consistent either: ``` > lst <- list() > lst[[""]] <- 1 > names(lst) [1] "" > list("" = 1) Error: attempt to use zero-length variable name ``` Should the parser be made to accept as valid what is otherwise possible

Thanks for the quick response Tomas. The same error is indeed happening when trying to have a zero-length variable name in an environment. The surprising bit is then "why is this happening during parsing" (that is why are variables assigned to an environment) ? We are otherwise aware that the error is not occurring in the R console, but can be traced to a call to R_ParseVector() in

Hi, I think this is a bug (even though I can't find documentation explicitly saying that it should work). Basically, Rf_PrintValue(obj) fails when 'obj' is an S4 object that should be printed using show() rather than print(). From the error message I'm guessing that the need to use show is detected correctly but then show is not found. "cbind2" in the code below is just

Is this expected behavior? > z <- 1:5 > z[1] <<- 0 Error in z[1] <<- 0 : object "z" not found The documentation seems to suggest that z will be found in the global environment and modified accordingly. Best, Hsiu-Khuern.

Reading the list of changes for R version 2.4.0, I was happy to see that the row names of dataframes can be stored compactly (as the integer n when row.names(df) is 1:n). help(row.names) contains this paragraph: Row names of the form '1:n' for 'n > 2' are stored internally in a compact form, which might be seen by calling 'attributes' but never via
