Hello... What does "na.pass"?
x=c(2.4, 2.4, 1.9, 2.5, 2.1) xNA=replace(x, 3, NA) p=c(acf(x, type=c("covariance"), plot=FALSE)$acf) pNA=c(acf(xNA, type=c("covariance"), na.action=na.pass, plot=FALSE)$acf) > p [1] 0.05040 -0.03112 0.00816 0.00224 -0.00448 > pNA [1] 0.02250 -0.01167 0.00250 -0.00100 -0.00250 In the manual say "na.pass returns objet unchanged"...
