[R] moving the x-axis in ggplot

Dear all, I was wondering if there is an easy way to set the position of the x-axis in ggplot with respect to where it intercepts the y-axis? The default is for the x-axis to be positioned at the bottom of the chart, but I would like to force it to intercept at y = 0 (I have both positive and nega

[R] ggplot and scale_x_date

Hi all, I have a question about setting arbitrary breaks/labels when using GGPLOT and date/time data on the x-axis. I want to specify the breaks/limits arbitrarily rather than using scale_x_date(major = 'blah'), much like when arbitrarily defining breaks/labels using scale_x_discrete(breaks = blah

[R] ggplot2 stacked line plot

Hi all, I have been hunting around for hours trying to figure out how to generate a stacked line chart using ggplot2. This type of chart can be generated in excel 2007 by selecting: Chart type > Line > Stacked line. I can generate a stacked area chart using the following code: p <- ggplot2(~,

[R] odbcConnectExcel2007 connection error

Hi all, Apologies if I violate any posting etiquette - this is my first submission to the R mailing list. I regularly use 'odbcConnectExcel2007' (from package 'RODBC') to read data from named ranges in excel workbooks into R. I recently received the following error message when attempting to set u
