New R-Packages: Triangle and LHS
...functions for
a triangle distribution (rtriangle, dtriangle, ptriangle, qtriangle).
The second package generates and augments Latin Hypercube Samples.
Functions for generating random and optimized designs are provided.
I look forward hearing your feedback and improving the documentation!

qunif() behavior with Inf arguments (PR#8958)
Full_Name: Rob Carnell
Version: 2.3.0
OS: Windows XP sp 2
Submission from: (NULL) (131.167.72.220)
Thank you for all you work on R project!
I noticed the following behavior today. It is what I believe to be an
inconsistency.
> qunif(.5, 0, Inf)
[1] Inf
> qunif(.5, -Inf, 1)
[1] NaN
Warning message:

Latin Hypercube with condition sum = 1
Hi
I want to du a sensitivity analysis using Latin Hypercubes. But my
parameters have to fulfill two conditions:
1) ranging from 0 to 1
2) have to sum up to 1
So far I am using the lhs package and am doing the following:
library(lhs)
ws <- improvedLHS(1000, 7)
wsSums <- rowSums(ws)
wss <- ws / wsSums
but I think I can't do that, as after the normalization
> min(wss)

problem with mode of marginal distriubtion of rdirichlet{gtools}
Hi all,
I have a problem using rdirichlet{gtools}.
For Dir( a1, a2, ..., a_n), its mode can be found at $( a_i -1)/ (
\sum_{i}a_i - n)$;
The means are $a_i / (\sum_{i} a_i ) $;
I tried to study the above properties using rdirichlet from gtools. The code
are:
##############
library(gtools)
alpha = c(1,3,9) #totoal=13
mean.expect = c(1/13, 3/13, 9/13)
mode.expect = c(0, 2/10, 8/10) #
