search for: xsel

Hi all, I created environment "mytoolbox" by : mytoolbox <- new.env(parent=baseenv()) Is there anyway I put it in the search path ? If you need some background : In a project, I often write some small functions, and load them into my workspace directly, so when I list the objects with ls(), it looks pretty messy. So I am wondering if it is possible to creat an

Hello list, I'm trying to generate classifiers for a certain task using several methods, one of them being decision trees. The doubts come when I want to estimate the cross-validation error of the generated tree: tree <- rpart(y~., data=data.frame(xsel, y), cp=0.00001) ptree <- prune(tree, cp=tree$cptable[which.min(tree$cptable[,"xerror"]),"CP"]) ptree$cptable CP nsplit rel error xerror xstd 1 0.33120000 0 1.0000 1.0000 0.02856022 2 0.08640000 1 0.6688 0.6704 0.02683544 3 0.02986667...

...h cat doesn't work on Windows, so I don't have any useful observations for that OS. You might say this is a weird example or use case. The actual usage where I discovered this is the way folks read/write the clipboard on macOS using pbcopy/pbpaste (and, in very similar ways, on linux using xsel or xclip). This is mentioned in the "Clipboard" section of the connections help topic. In 4.3.2 on macOS, I can successfully roundtrip with the clipboard: > pb_write <- pipe("pbcopy") > writeChar("hello clipboard!", pb_write, eos = NULL) > pb_read <- p...
