similar to: Sys.timezone (timedatectl) unnecessarily warns loudly

Hi all, I am testing R 4.0 and ran into an issue with timezones on Ubuntu Focal: converting a timestamp to another timezone results in NA: as.POSIXct(as.POSIXlt(Sys.time(), tz = "CET"), tz = "EST") This only happens on Ubuntu Focal, it seems to work fine on Ubuntu Bionic. I am the standard ubuntu docker image icw/ r-base from Dirk's ppa:edd/r-4.0 on both systems. Am I

I've noticed the following oddity where capture.output() prevents eval() from evaluating an expression in the specified environment. I'm not sure if it is an undocumented feature or a bug. It caused me many hours of troubleshooting. By posting it here, it might save someone else from doing the same exercise. Start by defining foo() which evaluates an expression locally in a given

>From this bug report (it's a proposal for speedup only, not a bug), https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16895#c6 the fact that you can construct factors with non-unique aka "duplicated" levels in R has been re-raised. As mentioned there, we had a small discussion here (on 'R-devel') a bit more than 7 years ago, where I had said that indeed R core had

I'm testing out quantstrat using a simple one-indicator strategy. The error I get after applyStrategy(...) is Error in .xts(e, .index(e1), .indexCLASS = indexClass(e1), .indexFORMAT = indexFormat(e1), : index length must match number of observations In addition: Warning messages: 1: In match.names(column, colnames(data)) : all columns not located in roc_15 for STOXX.Open STOXX.High

Thank you so much David, here is correction: d1=suppressWarnings(read.csv("/Users/anamaria/Downloads/B1.csv", stringsAsFactors=FALSE, header=TRUE)) d1$X <- NULL d2=as.matrix(sapply(d1, as.numeric)) pdf("~/graph.pdf") b<-barplot(d2, legend= c("SYCL", "CUDA"), beside= TRUE,las=2,cex.axis=0.7,cex.names=0.7,ylim=c(0,80), col=c("#9e9ac8",

Dear R useRs, with the following piece of code i try to find the first value which can be calculated without warnings `test` <- function(a) { repeat { ## hide warnings suppressWarnings(log(a)) if (exists("last.warning", envir = .GlobalEnv)) { a <- a + 0.1 ## clear existing warnings rm("last.warning", envir = .GlobalEnv) }

The suppressMessages and suppressWarnings functions currently suppress all the message or warnings that are generated by the input expression. The ability to suppress only specific messages or warnings is sometimes useful, particularly for cases like file import where there are lots of things that can go wrong. Suppressing only messages that match a regular expression has rightly been rejected

hi everyone, I want to backtest a simple strategy with RSI, im using "sigThreshold". i took example from the http://blog.fosstrading.com/ site to understand how quanstrat works. but now, i have a problem with my code that i really don't understand, R says me: Error in match.names(column, colnames(data)) : argument "column" is missing, with no default please can

Conditions have classes and the condition system is designed around the idea that classes would be used for this sort of thing. That is already how tryCatch and withCallingHandlers discriminate the conditions to handle. Designing and implementing a condition class hierarchy to support this is indeed the hard/tedious part.

I would like to propose adding a new plot function to the 'graphics' package. The new function is called areaplot() and I have implemented it as a generic function that supports a variety of data classes. An area plot consists of a simple line, like plot(x, y, type="l"), except the area between 0 and the line is a filled polygon. Areas can be stacked on top of each other,

I noticed that bsp, vp and ppp had no interrupt handler after investigating why 15% of my cpu time went to interrupts. nouveau was silent about it, but it should be an error since we have no way of acking in that case.

Hi All I've got an asterisk system, using a couple of Xorcom Astribanks to provide FXS ports. (I'm using the zaptel 1.2 branch, if that matters) I've noticed that the ringing volume is a lot louder than on our old phone system, and people are starting to complain it's too loud. (This is the noise the phone makes when it rings, not the noise in your handset when you ring

I'm building a new Ubuntu 16.04 machine, including Dovecot. When I select the dovecot-core package in Synaptic, it also wants to install ntpdate. Problem: ntpdate has been replaced in Ubuntu with timedatectl. In fact, if ntpdate exists on the machine, ntpd will not work properly. See: https://help.ubuntu.com/lts/serverguide/NTP.html See:
