Hi everyone,I have a question. Now I am reading the resource code of the package "ssfcov". The resource code is as following. I cannot find the resource code of the function "myss2d" anywhere in the package. Can anyone give me a hint how to find it in the package. Thanks a lot!!bv > ssfcov function (time, x, subject, nbasis = 5, centered = FALSE, noDiag = TRUE) { if (!centered) { fit<- smooth.spline(time, x) x<- x - fitted(fit) } gg<- NULL for (zz in unique(subject)) { if (sum(subject == zz)> 1) { tt<- time[subject == zz] xx<- x[subject == zz] g<- expand.grid(t1 = tt, t2 = tt) scov<- xx %*% t(xx) if (noDiag) scov<- scov + diag(rep(Inf, length(xx))) g$z<- matrix(scov, ncol = 1) gg<- rbind(gg, g[g$z< Inf, ]) } } nobs<- nrow(gg) tt<- min(time) + (max(time) - min(time)) * (1:nbasis)/(nbasis + 1) g<- expand.grid(t1 = tt, t2 = tt) g$z<- 0 gg<- rbind(gg, g) fit<- myss2d(z ~ t1 * t2, data = gg, id.basis = ((nobs + 1):(nobs + nbasis * nbasis))) class(fit)<- "rfcovObj" return(fit) } <environment: namespace:ssfcov>
Maybe I'm just slow tonight, but where did you get that package? I can't see on CRAN or R-Forge. You might also consider a more informative subject line. "Help needed" is true for all questions (not answers) on R-help. Just think, why is this list called R-***help***? Peter Ehlers
