1... and perhaps RcppEigen (after Rcpp and before lme4) – Ben Bolker Feb 10 '14 at 02:23

Thanks very much for the reply. I now changed the new version of R into the old version and this function works fine on the old version. – user3288202 Feb 10 '14 at 15:51

Just reinstalling Rcpp worked for me – Florian Hartig Feb 27 '14 at 10:22

Ran into this problem while using the `bobyqa` optimizer. Reinstalling `minqa` (which provides the currently used implementation though [this is expected to change](https://github.com/lme4/lme4/issues/98)) seems to fix this problem. – Livius Apr 16 '16 at 21:29

After a while, I got it.
1) Reinstall the latest version of Rcpp is the solution.
2) If you are not using lme4, but you also have this problem ("function 'dataptr' not provided by package 'Rcpp'") in combination with dyn.load(), it might be worth noting do not forget to include
library(Rcpp)
or
require(Rcpp)
on your code before
dyn.load("your_shared_lib.so")

why are you doing `dyn.load()`? Is this a solution to the error in a different context? (You shouldn't need `dyn.load()` if you're using `lme4` ...) – Ben Bolker Apr 11 '14 at 19:51

But I ended up in this question using google looking for a solution for " function 'dataptr' not provided by package 'Rcpp'", So I guess more people will end up here also when building their shared libraries – luis_js Apr 11 '14 at 20:32

OK, then, it would be good to make that clearer in your answer. There was an answer from Florian Hartig that was converted to a comment because it was so short (see above) ... – Ben Bolker Apr 11 '14 at 22:23
