similar to: proposal for new axis.Date/axis.POSIXct

Hi all. pretty() is now generic in R-2.12 and there are new methods for Date and POSIXt classes. These methods could potentially be used inside axis.Date and axis.POSIXt (and Axis methods), although that has not been decided yet. The main advantage of the new method is that it is flexible, in the sense that users can specify the desired number of ticks on an axis. (e.g. one could easily draw,

I recently called plot(x,y) where x was an array of POSIXct timestamps, and was pleasantly surprised that it produced a nice plot right out of the box: z <- as.POSIXct(c("2006-10-26 08:00:00 EDT","2007-10-25 12:00:00 EDT")) x <- seq(z[1],z[2],len=100) y <- 1:100 plot(x,y,type="l") The X axis had nice labels, one tick mark every other month. (Plotting on

Hi R-devel / R-core In the new pretty() methods for Date and POSIXct https://svn.r-project.org/R/trunk/src/library/grDevices/R/prettyDate.R there is currently a "pretty" time step listed as "15 DSTdays"... but this actually doesn't line up well with months. Much better to implement directly what this is trying to do: i.e. to have a "halfmonth" time step. This is

Env: Win XP, R 2.9.2] It's a minor annoyance, but I find that after I run example(), the console state of prompting to press Enter for each new graph remains as it is under example. It's more annoying that it seems difficult to turn this behavior off! In a fresh session: > getOption("example.ask") [1] "default" Run an example: > example(plot) plot>

hello I'm learning mgcv and would like to obtain numerical output corresponding to plot.gam. I can do so when seWithMean=FALSE (the default) but only approximately when seWithMean=TRUE. Can anyone show how to obtain the exact values? Alternatively, can you clarify the explanation in the manual "Note that, if seWithMean=TRUE, the confidence bands include the uncertainty about the

Hi, First, I do some calculation, then a plot. Add some lines and texts to the plot. Second, do some further calculation, then a plot. Add again some lines and texts to the plot. Third, do some further calculation, then.... Fourth, ..... After a plot is complete (means the plot itself, lines and texts) I would like to click 'enter' to see the next complete plot (again the plot itself,

Hello all and thanks in advance for any help, There are really two issues that I am having, both related to saving graphs: 1) It seems that the "dev...()" functions are unstable when using higher level graphs (specifically I was using levelplot) 2) I have a large grid of levelplot graphs that I can print out into a subset quite easily when I print to screen, but if I print to a

Hello, I'm trying to plot data that has gaps in the timeline because my data only has the business day in it. When I do a line plot I get the data and then a blank area where a line goes the tail of the last data point to the head of the next data point. Is there a way I can do a line plot where the gaps are not plotted? Thanks in advance, Brian > names(utildf) [1]

When plotting a reversed time axis with the base graphics system, R fails to label the axes. Example: times <- c(Sys.time() - 100, Sys.time()) plot(times, 1:2, xlim = times) # correctly labels the x-axis plot(times, 1:2, xlim = rev(times)) # fails to label the x-axis axis.POSIXct(1, times) # still fails to add labels dates <- c(Sys.Date() - 10, Sys.Date()) plot(dates, 1:2, xlim = dates)

Dear all I try to format labels on axis as standard ones does not look well, but I am not able to make axis.POSIXct to work. here is an example x<-seq(as.Date("2008-1-1"), as.Date("2009-9-6"), by="2 months") y<-rnorm(11) plot(x,y) #not very sophisticated axis plot(x,y, axes=F) axis(2) axis.POSIXct(1, at=x, format="%m/%Y") # no axis The same is on

Some time ago, I posted a note about what I considered to be a bug in axis.POSIXt() for R 2.8.x, relating to whether timezones in the data are obeyed on the axes. A link to that note, and to a quick and helpful response, is at the following URL http://www.nabble.com/patch-for-axis.POSIXct-%28related-to-timezones%29-td22338700.html#a22338700 Note that R 2.9.0 has been adjusted to help with

I believe I have found a bug (or at least a misfeature) in plot.POSIXct. See the following example code. set.seed(1) x=seq(1,1e8,length=100)+round(runif(100)*1e8) y=as.POSIXct(x,origin="2001-01-01") plot(y) This plots some random (date)times against their indices. The y axis correctly shows appropriate values (years), but the x axis contains the single number '59:58' in the

Hi I like to use "axis.POSIXct" to plot days from 2006 till 2008. But I only have datas for the summer months. Is it possible to get two axis breaks, to have not so long distances without points? thx Christof

I am using 'xyplot' in lattice to plot some data where the x-axis is a POSIXct date. I have data which spans a 6 month period, but when I plot it, only the last month is printed on the right hand side of the axis. I would have expected that at least I would have a beginning and an ending point so that I have a point of reference as to the time that the data spans. Here is some test

Full_Name: Karl Ove Hufthammer Version: 2.10.0 beta OS: Windows Submission from: (NULL) (93.124.134.66) When plotting a single POSIXct variable, 'plot' uses a nonsensical x axis. Here is some example code: set.seed(1) x=seq(1,1e8,length=100)+round(runif(100)*1e8) y=as.POSIXct(x,origin="2001-01-01") plot(y) The y axis correctly shows appropriate labels (years 2002 to 2006),

I have a series of datasets, each containing pH measurements and manufacturing dates, and each dataset pertains to a different manufactured product. I'm trying to create a series of plots of pH measurements by date, but the default X-axis labeling behavior is not giving adequate results in this particular case, and I can't figure out how to persuade R to come up with something more

I am finding that axis.POSIXct uses the local timezone for deciding where to put tic marks, even if the data being plotted are in another time zone. The solution is to use attr() to copy from the 'x' (provided as an argument) to the 'z' (used for the 'at' locations). I have pasted my proposed solution in section 1 below (as a diff). Then, in section 2, I'll put some

I've run into a problem with the datetime axis generated by axis.POSIXct. It appears a similar issue was discussed in October 2003 under the subject line "datetime data and plotting" (see https://stat.ethz.ch/pipermail/r-help/2003-October/039071.html), but I wasn't able to determine whether there is a straightforward solution. The code below produces a graph with apparently

Hello. I'd like to plot only one component smooth function of a gam model (for example the second) (library mgcv). So, I did : plot(my.gam, select=2, ask=F) But plot.gam doesn't seem to understand the "ask" option, so I can't deactivate the interactive plotting. I tried and failed by forcing it through : par(ask=F) And the "page" option of plot.gam (automatic

Hello. I would like to know if there is a command for stopping between multiple grpahs. I have a for in which I create a graph in each iteration. I would like R to wait for a click or an enter to pass to the next graph. Does anybody know how can this be done. Thank you Felipe Parra [[alternative HTML version deleted]]
