How to nest quantile() function within apply() function in R or RStudio
apply, console, quantile, r, rstudio
Solution
`tapply(data$x, data$y, quantile, probs=c(0.1,.2,.8,0.9), na.rm=TRUE)` ?
Problem
How can I nest a quantile() within a tapply() in R Studio? Given: ``` tapply(data$x,data$y, quantile) ``` This works, but it delivers standard quin-tiles. I want to choose custom percentiles. How can I incorporate something like this (below) into the above line of script? ``` quantile(data$x, c(0.1,.2,.8,0.9), na.rm=TRUE) ``` When I attempt to merge these, I receive the error message "match.fun(FUN)...not a function" Any ideas? Thanks,
