[R] Help with barplot
Hello all, I need to create a horizontal barplot with the following data: City Median Springfield 34 Worcester 66 Fitchburg 65 Lowell 63 Quincy 62 Boston 36 Cambridge54 Waltham 42 Medford 52 Pittsfield 65 Rensselaer 60 Schenectady 56 Glens Falls 64 The code below produces the bars for the Median, but how or where do I specify the corresponding city name on the y-axis for the bars. x-data.frame(City=ozone.ne.trim$City,Median=ozone.ne.trim$Median) with (x, barplot(Median,horiz=TRUE)) Please help.

Please relieve me my ignorance on one point: How does rbind(d[, 1], d[, 2]) differe from t(d)?

Re: [R] help on barplot
No practical difference in this case. Either way you end up with the matrix rotated 90 degrees. Presumably t(d) for a large d would be faster, however at 11:30 last night, using rbind() for some reason was the first approach that came to mind... ;-) Marc On Mon, 2003-07-21 at 08:30, Spencer Graves wrote: Please relieve me my ignorance on one point: How does rbind(d[, 1], d[, 2]) differe from t(d)?
