Hi, Does anyone know if the alternatives in the 'switch' function can be specified as strings containing spaces?  Neither of the two approaches below works. switch(expr, "Choice 1"="My first choice", "Choice 2"="My 2nd choice", "Choice 3"="My 3rd choice") x <- c("Choice 1", "Choice 2", "Choice

Hi, I have a data frame with column names "1", "2", "3", ... and I'd like to extract a subset based on the values in the first column. None of the methods I tried worked (below). x <- subset(dframe, 1 = = "My Text") x <- subset(dframe, "1" = = "My Text") x <- subset(dframe, names(dframe)[1] = = "My Text") Q

Hello, I'm trying to figure out how to find the index of the second occurrence of "/" in a string (which happens to represent a date) within a data frame column. I've used the following code successfully to find the first instance of "/". dframe <- data.frame(date=c("5/14/2011", "4/7/2011")) dframe$x1 <- regexpr("/", dframe[, 1])

Hello, I'm wondering if the 'mosaic' plot of the vcd package (or any other function for that matter) can be used with a continuous variable that should be represented via various categorical variables.  All the documentation I've read lead me to believe that it only works with counts of categories. Alternatively, I've thought of first creating a contingency table where the

Hello, Is there a way to set the maximum width of character columns when printing a data frame? I've looked into print(), format(), and options() and have been unsuccessful. For example, I'd like to achieve the results below without having to modify the data itself. > x <- data.frame(c1=rnorm(5), c2="ABCDEFGHIJKLMNOPQRSTUVWXYZ") > x c1 c2 1

I just joined this mail-list, so I apologize if this has been discussed before, but: Has anyone suggested adding a "todo list notation" to Markdown? Specifically, I'd like to see an open paren, brace or bracket, at the start of a line, followed by a space, a "/", or a "X", followed by a matching closing paren, brace, or bracket, followed by a space and more text

Hello, Does anybody know of a place to get a half-height PCI slot bracket for the Digium T100P card? I have an application to fit them in 1U cases for small, deployable PBX's. The T100P itself is short enough to fit in a half-height slot but I need an appropriate mounting bracket to screw it into the case. Thanks, Mark Hagler

Hi dear listers Do you know how to made a mean by one or more categorical variables? I can do that quite easy on SAS by in R I just can't do it E.g. Some fishes Sex Lenght male 15 fema 20 fema 17 fema 19 male 18 So the idea is mean(Lenght) by sex, in order to have sex: Male mean=XX Sex: Fema mean=YY In this case is quite easy to do it by a loop, but I have a huge DB so is not an

Hi Ralph Boehme, A new system is installed with Ubuntu 24.04.1 and Samba 4.19.5 My hotfolderscan.exe tool runs now on a Windows 2022 system and use the Ubuntu 24 system as Samba share.
