Dear List, I am want to plot my data in increasing order using the lattice barchart() function. I used order() to put my data in the order I want, but when I plot it I get the original order of the data. I think this has to do with the row index number since order() does not re-number the rows in the new order but instead keeps the original row numbers and puts them in a different order. For example:
xy<-data.frame(x=letters[1:5],y=c(3,9,2,1,10)) #This produces a dataframe in alphebitical order with row numbers in #numerical order. > xy x y 1 a 8.921657 2 b 10.314625 3 c 9.531537 4 d 10.818563 5 e 9.084872 #If I re-order the data based on the value of y xy<-xy[order(y),] #I get a dataframe ordered by y but the row numbers are still in #alphebetical order based on x > xy x y 1 a 8.921657 5 e 9.084872 3 c 9.531537 2 b 10.314625 4 d 10.818563 #I then try to plot the data and it plots it in alphabetical instead of #numeric order library(lattice) barchart(y~x, data=xy) Why are the rows not re-indexed, and how do I get barchart() to plot my data in increasing numeric order?
