similar to: Error in Calling C++ function from R!!!

Dear All, could someone please shed some light on the use of the .C or .Fortran function: I am trying load and running on R the following function // psi.cpp -- psi function for real arguments. // Algorithms and coefficient values from "Computation of Special // Functions", Zhang and Jin, John Wiley and Sons, 1996. // // (C) 2003, C. Bond. All rights reserved. // //

Dear all, I'm a newbie in R. I am running simulations using a fixed bandwidth in nonparametric regressions, sending all the output to a file myoutput.txt using sink("myoutput.txt"), & R is printing all warnings by the end of the simulation on the file. I know the source of the problem & can take care of it. However, finding a 50 MB file (where all the output is printed, e.g.

Dear all, The basename() function returns the extension also: > myfile <- "path1/path2/myoutput.txt" > basename(myfile) [1] "myoutput.txt" Is there any other function where it just returns plain base: "myoutput" i.e. without 'txt' - Gundala Viswanath Jakarta - Indonesia

I am a novice R user, and I am having difficulty understanding R's influence plots. I am trying to remove outliers from a particular variable, "sib." I am able to generate influence plots and further outlier information such as below (which is a shortened example). For my analyses, I end up excluding the points R refers to, 7, 18, 26, and 105. However, my question is, how can I

We do need an explicit method here, I think. The issue is that as() uses methods for the generic function coerce() but cannot use inheritance in the usual way (if it did, you would be immediately back with no change, since "integer" inherits from "numeric"). Copying in the general method for coercing to "numeric" as an explicit method for "integer" gives

As I tried to say on Dec. 11, there are two levels of "fix": 1. The fix to the complaint in the OP's subject heading is to conform to the default third argument, strict=TRUE: as(1L, "numeric") == 1.0 This generates some incompatibilities, as for classes that extend "numeric". But still leaves class(1.0) "numeric" and typeof(1.0) "double".

dear R wizards---I must be standing on the line (German translation---this must be obvious). This is probably embarrassingly obvious to anyone, except to me right now. maybe it is late. I would like to run my R code in batch, but not see the R compilations and my R source code---I just want to see the same output that I would see if I ran source("i.R"), but direct it to a file. I can

Calling parse(text=quote(name)) or text=as.name("name") makes parse() prompt for input from the command line and then it returns a parse of the initial characters of 'name' (depending on how many characters were typed at the prompt). E.g., > parse(text=quote(myName)) ?1/3 expression(myN) attr(,"srcfile") <text> >

Dear all, Every time that I need to generate I plot output as figure I use something like png("myoutput.png") plot(rnorm(100)*1.0,col=4) points(rnorm(100)*0.5,col=2,pch=0) dev.off() But now I need to generate a lot of outputs and it could not be done in a for looping where I can change the names. So I would like to know if is there a way of I automatically redirect the output from my

Dear All, I'm interested in creating a function similar to ns() from package splines that can be passed in a model formula. The idea is to produce "safe" predictions from a model using this function. As I have seen, to do this I need to use makepredictcall(). Consider the following toy example: myns <- function (x, df = NULL, knots = NULL, intercept = FALSE, Boundary.knots =

Somehow, the most obvious fixes are always back-incompatible these days. The example intrigued me, so I looked into it a bit (should have been doing something else, but ....) You're right that this is the proverbial thin-edge-of-the-wedge. The problem is in setDataPart(), which will be called whenever a class extends one of the vector types. It does as(value, dataClass) The key point is

Hi everyone, I did my homework and read the posting guideline :-) I want to eMail the results of a computing automatically. So I get the results (the parameters of a garch process) and I want to eMail them to another person. How can I do that?

Or maybe the "right" concept is that "numeric" is a virtual class with 3 subclasses: "complex", "double", and "integer". Anyway it's probably too late for implementing the "right" concept so it doesn't really matter. Thanks Martin for offering to fix the as(1L, "numeric") bug. Very much appreciated. I guess that means

When I attempt to compile R, I immediately get the error: 'make: file `Makefile' line 49: bad character & (octal 46) *** Error code 1 (bu21)' I have looked at line 49 of each of the makefiles and none of them seem to contain this character. Any suggestions? -- Cynthia Gibas cindy at mothership.champaign.il.us

Whats the reason that using a batch file can't be used with a remote destination? rsync --read-batch=foo /mysrc remote:/dest gives remote destination is not allowed with --read-batch I need to push the same set of files to about 20 servers and because of firewall rules, the 20 servers cannot pull from the central one. Thanks Kimo

I am hoping for some assistance with formatting a large text file which consists of a series of individual records. Each record includes specific labels/field names (a sample of 1 record (one of the longest ones) is below - at end of post. What I want to do is reformat the data, so that each individual record becomes a row (some cells will have a lot of text). For example, the column

Hello, I am relatively new to R and learning its ins and outs. As part of a website I am building, I need to read and write csv files directly from an SQL database. Basically I want to convert R variables (dataframes) into CSV format, store them as another R variable (as a properly formatted text string suitable for csv reading) and then send this to one row in a database. The SQL part is fine,
