Re: [R] Using Java methods in R

Thanks Icn for pointing that out, but I don't understand it. My use of .jcall to return a type double scalar or String worked. My use of .jfield to get a one dimensional static array worked. My use of .jfield to get a static scalar constant did not work. My use of .jfield to get a two dimensional s

Re: [R] Using Java methods in R

Thanks Icn for the lookup. I appreciate your skill. The static double field con0dbl started working for me too. I was surprised, and checked my code carefully. I think they corrected that in rJava. I download and install rJava each time I use R. Hill -- View this message in context: http://r.789

I don't know who to contact in the management of this R-forum, and there are a few things I cannot figure out. As I understand it, to participate and learn on the R-forum, I must receive all the emails even concerning topics I have no interest in currently. It clogs up my email, takes a long time

Re: [R] Using Java methods in R

H do I obtain a strictly rectangular type-double array (converted to an R 2-dimensional array) from a Java class? I can obtain a 1-dimensional type-double array (vector) or a scalar, but I cannot figure out the two-dimensional from the instructions. Is .jevalArray also involved? My simple Java te

Re: [R] Using Java methods in R

Hi Shekhar, Thank you. Right path. Sounds good. Please help me when you discover Java interface. Firstly, I don't know what the R symbol table is or how to do the checking you suggest. I am really naive about R. I want to be able to get my data in there so I can learn to use it for my purposes.

So the first few posts show that I found out how to get Java functions to return type double numbers to R. The arrays are still a problem. Here is another of my attempts to understand how to get java arrays into R. The Java code in class CalqsLin for an array of constants named conArr and for a

[R] index range

It looks to me like the index range starts at 1 in R. Is this true? If so, is there a way to change it to start at 0? That way, I wouldn't have to make so many changes when I translate a function from another language. -- View this message in context: http://www.nabble.com/index-range-tp15550797
