[R] How to sort a dataframe by one variable

Try RSiteSearch("Sort data frame").

Anyhow, use order() or sort.list() as follows:

dat[order(dat[,'myColumn']),]#Sorts data.frame dat by column "myColumn"
dat<-dat[sort.list(dat$myColumn, decreasing = T),] #Another option to do the 
same.  You can specify decreasing or increasing within both function

Cheers
