Is there any multivariate version of the function interp1 in R?

Question

I am looking for a way to compute the linear interpolation of a multivariate function (of 5 variables) using R. The package akima offer a way to compute the linear interpolation in the bivariate case. Is possible to perform the multivariate linear interpolation in matlab using the function interp, but I was wondering if there is a way to do the same in R.

Hope someone can help me! Thanks!

interp now provides this within r: https://rdrr.io/cran/npsp/man/interp.html & https://cran.r-project.org/web/packages/interp/interp.pdf
