lapply(list.dfs, function(x) x[order(x$var3), ])
will do the trick.
Question
If I have a list of data frames
list.dfs <- list(df1 = data.frame(var1 = c(1:3), var2 = c(1:3), var3 = c(1:3)),
df2 = data.frame(var1= c(1:3), var2 = c(1:3), var3 = c(1:3)),
df3 = data.frame(var1= c(1:3), var2 = c(1:3), var3 = c(3:1)))
How do I use lapply
and order to sort every data frame in the list by var3
(lowest to highest)
Solution
lapply(list.dfs, function(x) x[order(x$var3), ])
will do the trick.
