...basically like this: > x <- rlnorm(100,10,2) > f <- approxfun(1:100,x) > f(5) [1] 313811.3 > save(f, file="mytest_approx.Rdata") Now on 2.6.2, when I try to reuse the saved object I get an error: > attach("mytest_approx.Rdata") > f(5) Error in .C("R_approx", as.double(x), as.double(y), as.integer(n), xout = as.double(v), : C symbol name "R_approx" not in DLL for package "base" If I create the approxfun in 2.6.2 and use it in 2.5.0, I get a "mirrored" error: Error in .C("R_approx", as.double(x), as.dou...

....0 on windows and there seems to be a compatibility issue with objects that were created by "approxfun" in older versions. As long as the objects were created in version 2.7.0 things work ok, but calling the interpolated functions from R version 2.0.1 causes this error: Error in .C("R_approx", as.double(x), as.double(y), as.integer(n), xout = as.double(v), : C symbol name "R_approx" not in DLL for package "base" What's the problem and how can t be resolved (need to be compatible with old data)? Regards, K

Hi people, I am new in this list and could not find a FAQ for it in particular, furthermore I could not find my question answered in the official R FAQ or docs. I have simply something like this: > f<-approxfun(data[,1],data[,2]) and f is: > f function (v) .C("R_approx", as.double(x), as.double(y), as.integer(n), xout = as.double(v), as.integer(length(v)), as.integer(method), as.double(yleft), as.double(yright), as.double(f), NAOK = TRUE, PACKAGE = "base")$xout <environment: 02106C24> I also used "locPoly". Both yield eith...

...tion "f1." The last step in R is to generate f1 as the value of the approxfun function. I would like to put f1 into a package, but without having the package redo the creation of function f1. The value of approxfun is a function; for example, I have > f1 function (v) .C("R_approx", as.double(x), as.double(y), as.integer(n), xout = as.double(v), as.integer(length(v)), as.integer(method), as.double(yleft), as.double(yright), as.double(f), NAOK = TRUE, PACKAGE = "base") $xout <environment: 0x17719324> I don't really understand how this is...
