I am having a vector
monthData <- c("April", "June", "May", "August","July","September","December","November","October")
Is it possible to sort the vector in the chronological order of month name?
Thanks in advance

You can just use the built in month.name.
monthData[order(match(monthData, month.name))]
#> [1] "April" "May" "June" "July" "August" "September"
#> [7] "October" "November" "December"

You could transform the vector to a factorized vector:
fact_monthData<-factor(monthData, levels=month.name)
Then you can sort the vector by:
sort(fact_monthData)

You could try sort on another vector consisting of full dates, in the same year, with the various month components:
dates <- as.Date(paste0("2020-", monthData, "-01"), format="%Y-%b-%d")
monthData[order(dates)]
[1] "April" "May" "June" "July" "August" "September"
[7] "October" "November" "December"
Data:
monthData <- c("April", "June", "May", "August", "July", "September", "December",
"November","October")
