I am afraid that I do not know how rand generated in ge-model.cpp

<br>
Sorry for bothering you
much, but do me a favor
please. Please help me
some. <br>
<br>
I am just a molecular
biologist working on
plants. Thus, I am still
a newcomer in this
field. <br>
<br>
Recently, I have been
working with a script
using RcppArmadillo,
This has helped me a
lot. However, after
updating the system in
our institute, the
script gives me an error
repeatedly. My former
Postdoc wrote this
script. Thus, I did not
know this inside much. <br>
<br>
I have tried to fix it
for more than a month,
but now I have no idea
how to fix it. I would
appreciate it very much
if you could help and
give me your advice. <br>
<br>
Please see an attached
cpp file, termed
ge-r.cpp. With this cpp
file and other ones, I
have succeeded to
install a skeleton R
package into R using
your function
Rcpp.package.skeleton. <br>
<br>
In this ge-r.cpp, there
is one R function called
simulate_R() written. In
this R fucntion, there
are two C++ functions,
load() and simulate(),
both are described in
other cpp files, called
from C++ into R. With
cout function described
in simulate_R(), I
confirmed these two
function work in R
thanks to RcppArmadillo,
however, it suddenly
stops with an error,
address(nil) cause
'unknown' in R. It has
seemed to stop when it
return (out) at the last
in ge-r.cpp. I do not
know why it happens.
Note that the C++ script
works normally after the
update of the system.
Only this RcppArmadillo
conversion from C++
function into a R
function is deformed. <br>
<br>
Please give me an
advice, please. Of
course, I can give you
more information on the
C++ script in details if
you need. <br>
<br>
Best regards, <br>
<br>
Takeshi <br>
