But that is precisely what na.approx does. Here is an example: library(zoo) z <- as.zoo(ldeaths) z[c(4, 8, 17)] <- NA zz <- cbind(z, lag(z, -5)) plot(na.approx(zz), col = 1:2) # classic library(lattice) xyplot(na.approx(zz), col = 1:2) # lattice > Second, I have complex standard errors for each point, which are either > read in as a distinct column > for each y value or calculated in R and plotted with code such as (for the > first two series): > > plot(MP~dmp, type="b",xlab="",ylim=c(0,1),xaxt = "n") > arrows(dmp,MP+semp,dmp,MP-semp,length=.02,angle=90,code=3) > plot(C~dc, type="b",xlab="",ylim=c(0,1),xaxt = "n") > arrows(dc,C+sec,dc,C-sec,length=.02,angle=90,code=3) > I cannot get zoo to do this.
