How to sort all dataframes in a list of dataframes on the same column?

Question

I have a list of dataframes dataframes_list. For an example, I put the dput(dataframes_list) at the bottom. I want to sort all dataframes in the li

Answer 1

lapply is your friend ;)

You could do it using arrange from dplyr pacakge like this:

library(dplyr)
newlist <- lapply(dataframeslist, function(df){arrange(df,enrichment)})

or without dplyr like this:

newlist <- lapply(dataframeslist, function(df){df[order(df$enrichment),]})

Answer 2

Use lapply:

sorted_dataframes_list <- lapply(dataframes_list, function(df){
                                 df[order(df$enrichment),]
                                 })

Answer 3

This is a data.table solution.

require(data.table)

# Convert to data.table
dataframes_list <- lapply(dataframes_list, data.table)

# Setting a key sorts a data.table
lapply(dataframes_list, setkey, enrichment)
