...on the web site; I couldn't find anything on interpolation. So I started r and accessed the help (help.start()). (by the way is it possible to configure r to open help in opera instead of firefox?) Initially I read the help for the akima package but couldn't understand it. Next I tried the asplines package help. I tried to copy the example: x<-c(-3,-2,... I realised that the 'n=...' parameter determines the resolution of the line, so I practised the following subsequent commands: > x<-c(-3,-2,-1,0,1,2,2.5,3) > y<-c(0,0,0,0,-1,-1,0,2) > plot(x,y,ylim=c(-3,3)) I...

Hi, I am hired to translate into FORTRAN R functions. It works great and my customer is happy. I am going to translate a function that call aspline in the library AKIMA. This function call 2 FORTRAN routines that must be include (I guess) in the package AKIMA. And I have some questions. Is the fortran code really included in the R package AKIMA ? In other word, do I have a mean to call these 2 routines from a FORTRAN routine compiled in a D...

...erpolate single or two consecutive missing data points in time series. However, when it comes to longer gaps in the data the spline function generate new data for both my known and unknown data (see below). Aside from not understanding why this happens, I thought thought I might try function "aspline" in library (akima). However, I cannot install or find this library/package. Has anyone any instructions to install this package or help with my problem? Using this works.... > day<-c(1,2,3,4,5,6,7,8,9,10,11,12,13) > datfile<-c(16,23,39,37,45,34,NA,3,7,8,15,20,21) > for (i...
