Hi R-users, Can Maple function be exported to R? I have a jacobian matrix (4X4)?from maple in algebraic form which involve modified Bessel function of the first kind. I just wonder whether we can use algebraic form into R before the value of the parameters can be estimated. Thank you so much for your attention and help.

Hello list I have installed Maple 6 with no problems. It even put a shortcut on my Kubuntu Dapper Desktop but when I run Maple, I could see the splash screen then everything disappears. I don't know if this means that Maple 6 crashes. Any idea of troubleshooting? -- OOzy Kubuntu-Dapper

Hi. I was having trouble getting Greek letters and mathematical symbols in maple under wine, and a search turned up a few messages suggesting others have the same problem.

Sorry if asked before. I'm new to LLDB, try to use it according to the lldb project site. I write some very simple code like: #include <stdio.h> int main(int argc, char **argv) { int counter = 0; while ( counter < 10 ) counter++; printf("counter: %d\n", counter); return 0; } and the session like: $ clang -g main.c $ lldb-3.4 a.out (lldb)

Hi, I notice you're running a 32-bit program; are you also on a 32-bit host, or do you have a 64-bit OS installed? We don't generally test on 32-bit hosts, so it's possible you found a new bug. In addition, there are some known bugs with debugging 32-bit programs (even on 64-bit hosts) which will we hopefully be resolving soon. Nonetheless, I was unable to reproduce the behaviour you

I am trying to install my copy of maple 8 for windows, using wine in mandriva 2008.1. Apparently there is a difficulty with handling the java code for the installantion front-end. Below I report the log file showing the error. One curious thing is that I get very close to make wine run the maple 8 version I have already installed in a windows XP partition. The maple window correctly pops up, but

Hi all, I am interested in performing a cluster analysis on ecological data from forests in Pennsylvania. I would like to develop definitions for forest types (red maple forests, upland oak forests, etc.(AH AR in attached table)) based on measured attributes in each forest type. To do this, I would like to 'draw clusters' around forest types based on information from various tree

I am trying to follow the mclust examples in "MCLUST: Software for Model Based Clustering, Density Estimation and Disriminant Analysis" by Chris Fraley and Adrian Raftery, but I cannot reproduce the density and uncertainty surfaces for the Lansing Woods maples. I am using R 1.8.1 with the code below. The same code works fine in S-Plus 6.2 Am I missing something or is this a bug? Thanks Mike White library(mclust) data(lansing) # R only maples<-lansing[as.character(lansing[,"species"]) == "maple", -3] maplesBIC <- EMclust(map...

I wonder if there is a utility that enables Maple files to be imported into R? Many thanks. Andrew Philpott [[alternative HTML version deleted]]

Dear All, Hello! I have some questoins in R programming as follows: Question 1- How to take the integral of this function with respect to y, such that x would appear in the output after taking integral. f(x,y)=(0.1766*exp(-exp(y+lnx))*-exp(y+lnx))/(1-exp(-exp(y+lnx))) y in (-6.907,-1.246) It is doable in maple but not in R. At least I could not find the way. p.s: result from maple is:

Hi Firstly , happy Christmas to R-Help! Secondly, I wonder if anyone can help me with the following query: I am trying to reproduce some explicit probability calculations performed in APPL (a Maple extension for computational probability). For instance, in APPL, to compute the probability that the sum of 10 iid uniform variables [0,1] will be between 4 and 6, (i..e Pr( 4 < \sum_{i=1}^{10}X_i

Hi all! Does anyone knows if it exists a "symbolic math" package in R, that allows to compute derivatives, integrals, etc.? Does exist a freeware version of Maple? Cheers, Marco [[alternative HTML version deleted]]

Hi all, Is there any other packages to do numerical integration other than the default 'integrate'? Basically, I am integrating: integrate(function(x) dnorm(x,mu,sigma)/(1+exp(-x)),-Inf,Inf)$value The integration is ok provided sigma is >0. However, when mu=-1.645074 and sigma=17535.26 It stopped working. On the other hand, Maple gives me a value of 0.5005299403. It is an

Hi All, I was wodering if it is possible to increase the precision using R. I ran the script below in R and MAPLE and I got different results when k is large. Any idea how to fix this problem? thanks for your help for (k in 0:2000){ s=0 for(i in 0:k){ s=s+((-1)^i)*3456*(1+i*1/2000)^3000 } } -- View this message in context:

Hello, I am unable to figure out how to code a new column in a data frame based on an existing column that matches a column in a reference data frame, in a relational-db fashion. I would like this to maintain a minimum set of reference tables that may be reused over several similar datasets. Specifically, I have two data frames as listed below, 'Bos' and 'tree.' For each case in

Dear R-wizards! I have been learning on my own how to use this fantastic program.. but I agree with some people that even with the manuals, the faq and so on.. when you are sitting fully alone.. progress can be ... slow... very slow indeed.. In fact sometimes, looking at the "solutions" provided by some of you- I am just flabbergasted to the point that I couldn't figure out how to

I am working on a project that requires me to do very large factorial evaluations. On R the built in factorial function and the one I created both are not able to do factorials over 170. The first gives an error and mine return Inf. Is there a way to have R do these larger calculations (the calculator in accessories can do 10000 factorial and Maple can do even larger) -- View this message in
