[R] Strange behaviour of ISOdatetime

Hi All, I am watching a strange behaviour of ISOdatetime. In my work computer, I get NA when I try to do ISOdatetime(1995,03,26,2,0,0) [1] NA But on other dates and/or times (hour) works OK ISOdatetime(1995,03,25,2,0,0) [1] 1995-03-25 02:00:00 GMT In my home computer, I do not have this

[R] lwd gives different plotted line widths for Vertical and horizontal Lines when lwd= 2?

Dear All, I have been trying to add lines to the axis grobs of plots produced with ggplot2. The code I have used is below. It works, although I do not think it is a really elegant way of doing what I want However, I am now noticing that when plotted, the width of the lines in the axis

Re: [R] = vs. ==?

Hi. = means assignment (like a=2, may be used instead of a - 2, although I prefer to always use -); It is also used to pass values to arguments in named argument lists, or to set default argument values). == is the boolean (logical) operator for testing whether two values are equal e.g. a - 2

I just found out that this message got scrambled with other threads, so I trying to re-send... Dear R'ers, I am trying to build a composite plot (with several plots in one figure). I have tried, but I cannot use facetting, as I need to customize each plot using grid. Since all the plots are the

Dear R'ers, I am trying to build a composite plot (with several plots in one figure). I have tried, but I cannot use facetting, as I need to customize each plot using grid. Since all the plots are the same (with different data, but same layout and categories), I would like to have only one

[R] ggplot: Axis lines

Dear All, I am trying to print some simple ggplot plots, but I would like to have no gridlines, and no border. I have achieved this using ggopt(grid.lines='NA', border.lines='NA'). However, this also clears the axis lines, and reading the help, it looks like the axis objects have only two

Hadley, Thanks a lot! BTW, do you have any document explaining the object philosophy of ggplot? I was trying to see how you defined scale_fill_identity, but could not find it... Cheers, Pedro At 19:50 2008/04/01, hadley wickham wrote: However, it looks this works only when the data are in

[R] ggplot2 - facetting

Dear All, After having overcome the issue of legends (thanks, Thierry, once more), I am trying to use facetting, but here also I can not find how to do this. I do not want to use qplot, but rather the more flexible options. However, it seems I am doing still something pretty stupid, because I

[R] ggplot2 - legend for fill coulours

Dear All, I am trying to build a stacked bar plot, where I define the colours to use. I have asked this before, and I was using a solution in http://thread.gmane.org/gmane.comp.lang.r.general/100649/focus=100673 (thanks, Thierry). However, it looks this works only when the data are in the

[R] ggplot-How to define fill colours?

Dear R's (most likely Hadley), I want to build a stacked bar plot where I would like to define which colours will be used for each of the groups. However, I do not seem to find a way to do this, even if I've been looking over many places. I have tried several variations, and my final try was

[R] ggplot2 - getting at the grobs

Dear All, I continue trying to get several of my plotting functions to use ggplot, because I really do like the concept of the graphical objects, and working with them in the abstract. I am now trying to access the grobs to manipulate using grid. However, until now all I managed was to get the

[R] ggplot - Setting the y-scale in a bar plot

Dear All (probably Hadley), I am now trying to customise some plots using a bar geom. I do not want to use the default binning statistic, but rather calculate the bar heigths separately. I do manage this, but for comparison purposes I would like to have a set of plots all with the same y-axis

Re: [R] ggplot2 - expand range?

(0,10), expand = c(0,0)) ggplot uses expand_range internally to ensure that you always have some space between the data and the margins (and you should make sure this happens in your plot too - otherwise it can be hard to see data points on the sides) Hadley On 11/1/07, Pedro de Barros [EMAIL

[R] ggplot2 - expand range?

Dear UserRs, I am trying to use systematically ggplot2 for most of my plots, but I am fighting some lack of documentation, which I try to overcome. I want to build a scatterplot where the axes cross exactly at (0,0). I tried using scale_y_continuous(limits=c(0,10)), but I always get an extra

[R] reversing the scale on ggplot
