similar to: Suppress 'x' when appending to a csv file

That's amazing! Thank you!!! One follow up question, if that's OK? If, instead of using hard-coded CSV, I read the CSV into a variable first, then it fails again with a parse error. Code below. So, if I read the CSV into a variable, do I need an additional wrapper method? Seems like it should still work. Thanks in advance for your reply. -M String inputIris =

Hi all, Using RConsole, it's easy to get data from the database that you can use in an R Command. Like this: (Reference case) irisQuery <- dbGetQuery(conn, "select * from iris") boxM(irisQuery [,-5], irisQuery[,5]) ---- (Actual case this posting is about) Yet, if I'm getting that same (sample IRIS) data, say, in a web service possibly POSTED from a SQL command, that same

It can't be this hard, right? I really need a shove in the right direction here. Been spinning wheels for three days. Cannot get past the errors. I'm doing something wrong, obviously, since I can easily compute the Box's M right there in RStudio But I don't see what is wrong below with the coding equivalent. The entire code snippet is below. The code fails below on the call to

Hi All, OK, in the "back to the drawing board" department, I found what looks like a much better solution to using R in Java. Renjin. Looking at the docs and then trying a quick example, didn't quite work. Of course I'm missing something. Although I'm telling the engine to require ("biotools") just like I would in R itself, when I get to the line of code that

I'm not sure what you mean. Could you please be more specific? If I print the string, I get: boxM(boxMVariable[, -5], boxMVariable[, 5]) From this code: . . . // assign the data to a variable.rConnection.assign("boxMVariable", myDf); // create a string command with that variable name.String boxVariable = "boxM(boxMVariable[, -5], boxMVariable[, 5])";

Thanks Duncan. Awesome ideas! I think we're getting closer! I tried what you suggested and got a possibly better error... . . . rConnection.assign("boxMVariable", myDf); String resultBV = "str(boxMVariable)"; // your suggestion. RESULTING ERROR: Error in format.default(nam.ob, width = max(ncn), justify = "left") : invalid 'width' argument (No idea

Thanks! I just figured it out (thanks to "Beyond Compare") and was coming here to post back. The boxM test doesn't work with that (now, finally working) REXP structure, but I probably now need to create a table or something and parse that structure. So much fun! :) Thanks again. - M Sent from [ProtonMail](https://protonmail.com), Swiss-based encrypted email. > --------

Hey Duncan, Hard to debug? That's an understatement. Eyes bleeding.... In any case, I tried all your suggestions. To get "integer" for the final column, I had to change the code to get integers instead of strings. double[] d1 = ((REXPVector) ((RList) tableRead).get(0)).asDoubles(); double[] d2 = ((REXPVector) ((RList) tableRead).get(1)).asDoubles(); double[] d3 = ((REXPVector)

Thanks Duncan. I can't tell you how helpful all your terrific replies have been. I think the biggest surprise is that nobody appears to be using Java and R together like I"m trying to do. I suppose it should be a surprise since there are no books on the subject and almost no technical documentation other than a few sites here and there. ----- I originally had the "int" as the

You are entering the quoting hell - you are missing quotes and escapes for \n. it would be much more reasonable to use the rConnection.assign method instead of pasting any content through the parser.

I suspect that you are looking for something like: read.csv(textConnection( "5.1,3.5,1.4,0.2,setosa 4.9,3,1.4,0.2,setosa 4.7,3.2,1.3,0.2,setosa 4.6,3.1,1.5,0.2,setosa 5,3.6,1.4,0.2,setosa" ), header = FALSE) HTH, Jan On 25-10-17 12:50, Morkus via R-devel wrote: > Hi all, > > Using RConsole, it's easy to get data from the database that you can use in an R Command.

Just print the string you are asking to R to evaluate. It doesn't make any sense as an R expression. Fix that, and things will work.

Does it work if you supply the closing parenthesis on the call to boxM? The parser says the input is incomplete and a missing closing parenthesis would cause that error.. // create a string command with that variable name.String boxVariable = "boxM(boxMVariable [,-5], boxMVariable[,5]"; // try to execute the command... // FAILS with org.rosuda.REngine.Rserve.RserveException: eval

Renjin is not R.?? Renjin is an R language interpreter written in Java. It has become exceedingly obvious that you are making user errors.??That's not a bug in the language. If you want to use Renjin, there are mailing lists devoted to Renjin, and also Stack Overflow and Renjin list questions that cover exactly what you've asked about (loading packages in Renjin when Renjin is used as a

Hi, I am using Sweave for chapters in my thesis that contain results. In the beginning of each chapter, I use this to load libraries I need. <<init,echo=FALSE,quiet=TRUE>>= library(gplots) library(Hmisc) library(e1071) @ What I want is, of course, to supress messages written by this code, but what I get in the end is X-init.tex with this the contents below. How do I really supress

Hi, Is there any way that I can supress error messages so that they don't stop for loops running? I'm using the gstat package and have created a variogram model for the double exponential model: "dexp <- vgm( .5, "Exp", 10,.1, add.to = vgm(.5, "Exp", 100))" and fitted it using "dexp.fit <- fit.variogram(temp2, dexp, fit.method=6,

Hi all, several packages print messages during loading. How do I avoid to see them when the packages are in the defaultPackages? Here is an example. With this in ~/.Rprofile ,----[ ~/.Rprofile ] | old <- getOption("defaultPackages") | options(defaultPackages = c(old, "filehash")) | rm(old) `---- I get as last line when starting R: ,---- | filehash: Simple key-value
