this does not necessary to prepare large amount of RAM.```{r} na_func x[x return(as.vector(x)) }stk system.time(ans summary(ans) ``` user system elapsed 10.585 0.254 10.898 #### calculation for temporal interpolating NA values in raster st…
this approach depends on RAM. it is only faster when using smaller raster data. Do not try this way if you use big raster data.```{r} system.time(stk[stk summary(stk) ``````{r} system.time(stk[stk summary(stk) ``` user system elapsed 0.984…
