Hello, I'm very much a newbie in R and more so in tcltk so apologies if this question is stupid. Basically I am trying to use the combobox example found here: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/DropDown.html . What I want to do is in that example get fruitChoice as a variable in R in general. When I run that code, however, and the ask for fruitChoice it says

Hello I've created a 3d scatterplot, and had no problems labeling the points. However, I've been really struggling to change the color of the points based on a factor (see 'group' below). Is such a thing possible? My data look like this: food group x y z apple fruit 0.216 -0.112 -0.893 orange fruit 0.814 0.097 0.460 broccoli veg -0.239 0.240 -0.425 banana

Thank you for your help! I gave you an example, you could run it in R . Maybe you will understand my meaning clearly. x <- data.frame(main.name="AAA", x.name=rep(c("Apply","Watermelon","Lemon","Banana",

Hello all, I am new to R and my question should be trivial. I need to create a word cloud from a txt file containing the words and their occurrence number. For that purposes I am using the snippets package [1]. As it can be seen at the bottom of the link, first I have to create a vector (is that right that words is a vector?) like bellow. > words <- c(apple=10, pie=14, orange=5, fruit=4)

Hello everyone, I have the following problem: My analysis includes many predictor variables (>50) in the form of raster maps (asc), but I am trying to avoid having to type all their names over and over again in the analysis (e.g. for vectorisation, for deletion of NA's, etc.) So ideally I would like to store them in some way that their names only have to be typed once and can always

Hi all, Suppose I have a vector Fruits <- c('Apple','Orange','Pear','Banana','Mango') I want to print the statement "The fruits in the basket are: Apple, Orange, Pear, Banana, Mango" If I do: print(paste('The fruits in the basket are:',Fruits)) The output is: [1] "The fruits in the basket are: Apple" "The fruits in

Hi everyone, I wonder if I can get your help using a custom function in apply. Imagine the following dataframe called "data": LowLim HighLim A1 A2 A3 A4 4 6 3 4 5 6 4 6 4 5 5 6 2 3 1 4 2 3 2 3 NA NA NA NA We have created a custom function (see below) that takes the values in a given row between columns A1 to A4 to see if they are outside the limits in the same

I've encountered something that didn't arise using earlier versions of R (Linux). A dataframe is created and new columns added to it by doing calculations using apply with various functions on some of the original columns. It's somewhat too involved to give a toy example that's reproducible. However, the resulting phenemonon can be characterised by the following: Browse[1]>

Hi Im confused by one thing, and if someone can explain it I would be a happy > rev(strsplit("hej",NULL)) [[1]] [1] "h" "e" "j" > lapply(strsplit("hej",NULL),rev) [[1]] [1] "j" "e" "h" Why dossent the first one work? What is it in R that "fails" so to say that you need to use lapply for it to get

I?m not sure if this is related, but there was a regression a while back in handling resource forks in folder icons.

As soon as i try to add a color tag (e.g. yellow) with Mac OS 10.15.5, the tag appears shortly but hides one second later. The file system is ZFS with no special options configured. I tried the Ubuntu package but also the builds from source
