similar to: Issue with getParserData in R3.0.0

Prior to R-3.6.0 the keys in the lazyload key files, e.g. pkg/data/Rdata.rdx or pkg/R/pkg.rdx, seemed to all be 2-long integer vectors. Now they can be lists. The ones I have seen have two components, "eagerKey" is a 2-long integer vector and "lazyKeys" is a named list of 2-long integer vectors. > rdx <- readRDS(system.file(package="survival",

Hi, I have run into a problem with parseData from the utils package.? When an assignment is done with = instead of <-, the information provided by parseData does not include an entry for the assignment. For this input, stored in file "BadPosition.R": y <- 5 foo = 7 And running this code: parsed <- parse("BadPosition.R", keep.source=TRUE) parsedData <-

The fix is now in R-devel, 75386. I have not ported to R-patched, because the fix breaks two packages which are working around this bug (and to my knowledge without having reported it before). So thanks again for the report! Best Tomas On 08/16/2018 10:06 AM, Tomas Kalibera wrote: > Dear Barbara, > > thank you for the report. This is something to be fixed in R - I am > now

Under some specific conditions, `parse` seems to produce inconsistent and potentially incorrect results the first time it is run in a fresh clean R session.? Consider this code where we parse the same text twice in a row, and get one value in the parse data that is mismatched: ```Type 'demo()' for some demos, 'help()' for on-line help, or 'help.start()' for an HTML browser

I am at a complete loss here and I need a solution asap! Any help is GREATLY appreciated!!! I have my request going out to a php script that sends a query to my db and then echos the return data into html format. this script works fine when I go to the url in a browser and send the correct params. However, in my ajax request, nothing gets returned?! Here is my code...

I noticed the following file descriptor leak when I couldn't remove a package unless I shut down the R session that had loaded and used it. The function that triggered the problem printed the output of a call to parse(). Each time one prints a srcref a connection is opened and not closed. It looks like it happens in as.character.srcref's call to getSrcLines, which has some logic I

I get an R error and no segfault: > parse(textConnection(text), srcfile = srcfile) Error in parse(textConnection(text), srcfile = srcfile) : test.r:1:1: unexpected $end 1: ? ^ This is R 4.3.0, so maybe the bug has been introduced since then...

Hi all, When I run the following code, R segfaults: text <- "?" srcfile <- srcfilecopy("test.r", text) parse(textConnection(text), srcfile = srcfile) It doesn't segfault if text is ASCII, or it's not wrapped in textConnection, or srcfile isn't set.

Thanks, this is

Hello there! Somebody tried the meetme|b which initiates the conf-background AGI. Actually I want to originate another call from a conference.my AGI originates the call and connects it to the conference, but the calleeee is nowhere My extension exten => 21,1,meetme(21|pb) and my AGI **************************************************************************** #!/usr/bin/perl -w

Hello, I have R as a socket server that computes R code sent by some scripts (the clients). These scrips send R code to generate models (SVM). The problem is that first models are generated in less than one second and one hour later, the same models are generated in more than ten seconds (even training with same data). If I restart the server , then it works well (fast). I don't know if I have

Hello everybody!!! I really need your help guys, I am using the AGI mode in meetme application, and I want that AGI should wait for an input from the client/user i.e. a digit and then proceed, but I have used that AGI function agi->wait_for_digit(), but no use....my agi just passes, or ignores this function, where AGI should stop here and wait for the input.... .....my extension in my

In my .Rprofile I have the following functions which display the current directory in the main R window title bar, and modify base::setwd() to keep this up to date. I like this because I can always tell where I am in the file system. cd <- function(dir) { base::setwd(dir) utils::setWindowTitle( short.path(base::getwd()) ) } short.path <- function(dir, len=2) { np

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 Barbara, thank you for the report. This is something to be fixed in R - I am now testing a patch that adds the extra node for the equality assignment expression.

In R <= 2.13.x, calling 'parse( con)' where 'con' is a connection, 'options( keep.source)' is TRUE, and default 'srcfile' would preserve the source. In R >= 2.14.1, it doesn't. > tf <- tempfile() > options( keep.source=TRUE) > texto <- c( 'function() { # comment', '}') > parse( text=texto) expression(function() { #

Hi Duncan ? Wonderful. Thank you. Bug or no bug, I think it would be a huge improvement for user-friendliness if R printed the last line by default *every time* a script dies. Most computer languages do so. Should I file it as a request for improvement to the R code development team? Maybe R can be improved at a very low cost to the development team and a very high benefit to newbies.

Hi, I would like to use the curve() function to draw the predicted curve from an nls() object. for example: dd<-read.table("dd.txt",sep='\t',header=T,row.names=1) obj<-nls(y~c+(d-c)/(1+(x/e)^b),data=dd,start=list(b=-1, c=0, d=100, e=150)) coef(obj) b c d e -1.1416422 0.6987028 102.8613176 135.9373131
