Re: [R] Inserting rows of interpolated data

Hi Jon, zoo is great for tasks like this, not just for na.approx. :) I would approach the problem like this: library(zoo) # put lightdata into a zoo object z <- with(lightdata, zoo(light, as.POSIXct(paste(date, time), format="%m/%d/%y %H:%M:%S"))) # merge the above zoo object with an "empty" z

Re: [R] Inserting rows of interpolated data

Hi Why you do not change date and time to POSIX object? It is simple and saves you a lot of frustration when merging two data frames. If you changed lightdata date and time to new column lightdata$newdate <- strptime(paste(lightdata$date, lightdata$time, sep=" "), format = "%d/%m/%y %H:%M:%S")
