How to use tapply for quantile
I am trying to calculate quantiles of a data frame column split up by
two factors:
# Calculate the quantiles
quarts = tapply(gdf$tt, list(gdf$Runway, gdf$OnHour), FUN=quantile,
na.rm = TRUE)
This does not work:
> quarts
04L 04R 15R 22L 22R 27 32
33L 33R
0 NULL Numeric,5 NULL Numeric,5 NULL Numeric,5 NULL
Numeric,5 NULL
1 NULL Numeric,5 NULL Numeric,5 NULL NULL NULL
Numeric,5 NULL
2 NULL NULL NULL Numeric,5 NULL NULL...
