I have free text data in a single text document. I create a corpus, and then a document term matrix out of it. I can create a word cloud too. But when I do word association for the same, using "findAssocs(), it always returns numeric(0). EX : findAssocs(dtm, "king" ,000000000000000000000.1) I read on stack overflow that it is because I have a single document. What is the workaround for the same ? [[alternative HTML version deleted]]

Hello Experts, I'm new with R and having troubles doing my graduation project.I have 20 subfolders including almost 20000 txt files.What i need to do is to create a dtm and add a column to it showing a "class" information of the txt files. My directory source is like "C:\\R\\20news-18828\\comp.graphics" for the comp.graphic subfolder.I need to take only "comp.graphic" part to be seen at the CLASS column.Pleasehelp... -- View this me...

If you consider the definition of a DTM, and that findAssoc() computes associations between words as correlations across documents(!), you will realize that you can't what you want from a single document. Indeed, what kind of an "association" would you even be looking for? B. > On Nov 15, 2017, at 12:40 AM, Rahul sin...

Hello everybody, I am a new R & Grass user. I am interested in doing a kriging of the Temperature in a basin, based on pixel elevation (DTM). I use Grass 6.2.1 and R 2.5.1 and have installed the spgrass6 package. The DTM is called "DTM_trentino_100m" and is like this: north:5158000.0 south:5058500.0 east:1729700.0 west:1611600.0 rows:995 cols:1181 -9999.0 -9999.0 -9999.0 370.84381103515625 372.55120849609375 373.131286621...

Hello, I'm having problems working with date values in POSIXct format. Here is what I got (eg.lig attached): x <- read.table("eg.txt", sep = ',', col.names=c("ok","time","secs","lig")) # it gives time as factor z <- cbind(x,colsplit(x$time, split="\\s", names=c("date", "clock")))

I am trying to find the math behind the "tm" package findAssocs() ?findAssocs does not say anything besides "association" and "correlate" Usually entering "findAssocs" at the CLI gives the code for a R function, but in this case I obtain: function (x, term, corlimit) UseMethod("findAssocs", x) <environment: namespace:tm> Any ideas?

I have installed Skype 4.0.0.8 on my new workstation running CentOS-6.3 (kvm) and the Gnome DTM. This host has an Intel DG43GT motherboard with on-board audio. The sound works when tested in the sound preferences in the desk top. Skype runs and the integrated usb video and microphone both work (I infer this from the mic test in Skype options showing movement on the intensity bar as I can h...

You can use regular expressions. ?regex and/or the stringr package are good places to start. Of course, you have to define "stop words."
