Re: [R] Query concerning working directory for file.choose()

Thanks Duncan. The behaviour is tricky, and I'm still not sure I can predict it. Indeed, I spent about an hour fiddling with file.choose(). It allows navigation across directories, so is not totally without value. However, I've noticed users are very prone to making errors when they aren't in t

Yes, this is different in RStudio, e.g. I had actually forgotten how brain-dead the CLI version is: > file.choose() Enter file name: (Given that install.packages() fires up a Tcl/Tk chooser, users might reasonably expect us to do something at least slightly smarter). - Peter > On 18 Dec 2024

Re: [R] Query concerning working directory for file.choose()

I believe file.choose() remembers the last choice, and repeats that location the next time you call it. This is true when it is called at top level or from within a function. The first time you call it in a session, it will default to the current working directory, but not after that. Front

Hi Bhaskar, Maybe: df1 <-read.table(text="time v1 v2 v3 1 2 3 4 2 5 6 4 3 1 3 4 4 1 3 4 5 2 3 4 6 2 3 4", header=TRUE) df2 <-read.table(text="time v11 v12 v13 3 112 3 4 4 112 3 4", header=TRUE) for(time1 in df1$time) { time2<-which(df2$

Or use rownames and subscripting? df1 <- read.table( text= "time v1 v2 v3 1 2 3 4 2 5 6 4 3 1 3 4 4 1 3 4 5 2 3 4 6 2 3 4 ",header=TRUE) df2 <- read.table( text= "time v11 v12 v13 3 112 3 4 4 112 3 4 ",header=TRUE) df3 <- df1 rownames( d

Re: [R] Query - Merging and conditional replacement of values in a data frame

Your "assignments" (<-) are not legitimate R code that can be cut and pasted. Learn to use dput() to provide examples that we can use. You fail to say whether the time column of df2 is a proper subset of df1 or may contain times not in df1. I shall assume the latter. You also did not say whether t

Hi you can follow logic of functions by using debug and see how they operate by inspecting objects evaluated within functions. See ?debug However it seems to me that your functions are quite complicated. If I understand correctly, they compute minimum value of upper part of matrix. If I am co

Re: [R] Query about use of format in strptime

Hi Stefano, As the help page says: "The default for the format methods is "%Y-%m-%d %H:%M:%S" if any element has a time component which is not midnight, and "%Y-%m-%d" otherwise. This is because when the result is printed, it uses the default format. If you want a specified output representation:
