Hey all, what is wrong with this command: system2("echo", env = c(VAR = "Hello World"), args = c("$VAR")) I am a bit confused, as help("system2") writes about the env option: > character vector of name=value strings to set environment variables. Is this option buggy, or am I using it just wrong? Thanks for your help Henning

hi. i'd like to instantiate sed(1), send it some input, and retrieve its output, all via pipes (rather than an intermediate file). my sense from pipe and looking at the sources (sys-unix.c) is that is not possible. is that true? are there any thoughts of providing such a facility? cheers, Greg

I am not sure if `pipe()` works for this, but if it turns out that it does not, then you can use the processx package, e.g.: > p <- processx::process$new("sed", c("-l", "s/a/x/g"), stdin = "|", stdout = "|") > p$write_input("foobar\n") > p$read_output() [1] "foobxr\n" The `-l` sed flag is to make sed line-buffered, otherwis...
