<br>
<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>
