na.locf is replaced by
The functionality stays the same. The new name better fits modern R code
style guidelines (which prefer _ over . in function names).
na.locf(x, option = "locf", na.remaining = "rev", maxgap = Inf, ...)
Algorithm to be used. Accepts the following input:
"locf" - for Last Observation Carried Forward (default choice)
"nocb" - for Next Observation Carried Backward
Maximum number of successive NAs to still perform imputation on. Default setting is to replace all NAs without restrictions. With this option set, consecutive NAs runs, that are longer than 'maxgap' will be left NA. This option mostly makes sense if you want to treat long runs of NA afterwards separately.
