[R] Scriptable Integration

[R. Michael Weylandt]

I'm not quite sure what you mean, but perhaps this will help:

library(splines)
mydata <- structure(list(V1 = c(1328565067, 1328565067.05, 1328565067.1,
1328565067.15, 1328565067.2, 1328565067.25), V2 = c(0.0963890795246276,
0.227296347215609, 0.240972698811569, 0.221208948983498, 0.230898231782485,
0.203282153087549), V3 = c(0.0245045248243853, 0.0835679411703579,
0.0612613120609633, 0.058568910563872, 0.0511868450318788, 0.0557714205674231
)), .Names = c("V1", "V2", "V3"), row.names = c(NA, 6L), class = "data.frame")

spf <- splinefun(mydata$V2)
splInt <- function(low, up) integrate(spf, low, up)$value

splInt(0, 1)

splInt(0, 2)
