Hi: I need some help. I am ploting a bar graph but I can't adjust my x axis scale I use this code: i <- qplot(ForkLength,Number,data=FL,geom="bar") i + geom_bar(colour="blue",fill="grey65") # too crowded FL_dat <- ggplot(FL,aes(x=ForkLength,y=Number)) + geom_bar(colour="green",fill="grey65") FL_dat +

Hi everyone: I did this before with R and I can't remember how. I got some fish forklength values FL number 34 4 35 3 36 7 I need to breakdown the FL by the number of fish with the same length like this: 34 1 34 1 34 1 34 1 35 1 35 1 35 1 36 1 36 1 36 1 36 1 36 1 36 1 36 1 Felipe D.

Hi: Since I didn't get any answers, I'll refresh my question. I have a dataset called "Chinook Run" saved in Excel and I want it to be loaded everytime R starts, so I can call it with a statement like the one below: qplot(color, Year/Forklength, data = Chinook Run) I wonder how can I do that. I went to the rprofile.site and copied the path to my dataset there and it

Hi: I need some help with the legend. I got 14 samples(Muestreo) and I am trying to plot a smooth line for each sample. I am able to accomplish that but the problem is that the legend only displays every other sample. How can I force the legend to show all of my Muestreos? Thanks in advance. fish_ByMuestreo <- structure(list(data = structure(list(SampleDate = structure(c(3L, 3L, 3L, 3L,

Manuel: I changed your variable names from x to 'long' and y to 'lat' on the riqueza_out.csv file. The code below should do what you want. Also, since the legend title is kind of long, I broke it down into three lines so you can see more plot area. I am cc'ing the other groups so more people use it if needed. library(rgdal) library(ggplot2) library(sp) library(maptools)

The reason I want to be able to do this is because I have developed and application with Visual Basic where Word,Access and Excel "talk" to each other and I want to integrate R to this application to estimate confidence intervals on fish sizes (mm). I basically want to
