enter image description here

i tried using rownames, can't figure out how sort row names date, july 28 becomes '2', july 29 becomes '3', etc. have way achieve this? if additional information needed, please let me know. in advance!

you can use built-in order function:

newdata <- df[order(df$date),]

if rownames persist out of order, can reset them:

rownames(newdata) <- null
