newbie: new_data_frame <- selected set of rows
#Mock df creation
my_dataframe <-data.frame(matrix(runif(14*5),14,5))
row.names(my_dataframe) <-paste("ENSP",1:14,sep="")
distances <-c(13,14,10 ,11, 2, 4, 6, 1, 3, 9, 8, 12, 7, 5)
head(my_dataframe[order(distances),],5)

distances
[1] 13 14 10 11 2 4 6 1 3 9 8 12 7 5 #numbers correspond to rows in my_dataframe
my_dataframe
V2 V3 V4 V5 V6 ENSP00000354687 35660.45 0.04794521 0.05479452 0.06849315 0.07534247 ENSP00000355046 38942.77 0.02967359 0.04451039 0.04451039 0.06824926 ENSP00000354499 57041.21 0.04700855 0.08760684 0.11965812 0.06196581 ENSP00000354687 etc are rownames. I am trying to get top five row names with smallest distances from a given vector as calculated by distancevector from hopach. Darek Kedra
