I am running into a wall getting my system to work with rcpp and inline.
Following Dirk's advice on stackoverflow, I hope someone is able to help
me.
My steps were to install MinGW 32 bit first, then installing Rtools, I
disabled MinGW's entry in the PATH.
I am trying to get the following code to work:
library(Rcpp)
library(inline)
body <- '
NumericVector xx(x);
return wrap( std::accumulate( xx.begin(), xx.end(), 0.0));'
add <- cxxfunction(signature(x = "numeric"), body, plugin = "Rcpp",
verbose=T)
x <- 1
y <- 2
res <- add(c(x, y))
res
I get the following error messages:
