similar to: How to unlist Dates

Reading the body of function 'AnswerType' in bind.c, called from 'do_c' and 'do_unlist', I notice that EXPRSXP and VECSXP are handled identically in the recurse = TRUE case. A corollary is that c(recursive = TRUE) and unlist(recursive = TRUE) treat expression vectors like expression(a, b) as lists of symbols and calls. And since they treat symbols and calls as

If I run the following example from: http://www.stat.auckland.ac.nz/~paul/grid/doc/grobs.pdf > grid.newpage() > pushViewport(viewport(w = 0.5, h = 0.5)) > myplot <- gTree(name = "myplot", children = gList(rectGrob(name = "box", + gp = gpar(col = "grey")), xaxisGrob(name = "xaxis"))) > grid.draw(myplot) >

Dear all, I have a large vector (lets call it myVector) and I want to plot its value with the logic below yaxis<-myVector[1] yaxis<-c(xaxis,mean(myvector[2:3]) yaxis<-c(xaxis,mean(myvector[4:8]) yaxis<c(xaxis,mean(myvector[9:16]) yaxis<c(xaxis,mean(myvector[17:32]) this has to stop when the new ..... yaxis<c(xaxis,mean(myvector[1024:2048]) will not find the correspondent number

Hi R list, I like the default ticks that are set up using grid.xaxis() or grid.yaxis() with no arguments. Finding good values for the 'at' argument is usually not a trivial task; the default behavior of these functions seems to work well. The problem with this strategy is that I cannot figure out how to "recover" the positions of these ticks when you do NOT specify the

Dear list, Can someone explain why the childNames below gives character(0) instead of the (canonical) names of the children grobs of the xaxis gTree ? [1] "major" "ticks" "labels" Many thanks in advance, Tobias ### minimal example code ### library(grid) pushViewport(plotViewport(c(5,4,4,2))) pushViewport(dataViewport(1:5, 1:5)) grid.points(1:5, 1:5)

I have some code as shown below. Basically, I would like three boxplots to be set next to each other with no ylabels on the two "inner" plots, and I want the same x axis range on all three. However, it seems like boxplot does not respect the xlim setting. I've tried the various ways I thought would work (par, boxplot(...xlim=)) but none of them seem to work. I then tried plot.window,

Hello, I am trying to create a graphic to help me visualise data. A (very simplified) sample of the data is http://n4.nabble.com/file/n1839676/circle_data.txt circle_data.txt : Aug-07 Nov-07 Feb-08 data1 1 1.5 -1 data2 1 1.2 1.6 data3 1.3 1.4 1.8 data4 1.3

Hi, I try to create a vertical line in my plot, which has a xaxis comprising time formated data. This is what I tried: ---------------- y<-152833 x<-strptime(y, format="%H%M%S") abline(v=x, col="red") ---------------- for some reason, it doesn't work and no error msg is displayed... I hope someone can tell me what I do wrong, or maybe an alternative. Thanks

unlist(recursive=FALSE) returns NULL elements when passed a nested pairlist containing non-NULL data: x <- pairlist(pairlist(1:2)) unlist(x, recursive=FALSE) ## [[1]] ## NULL version 2.7.2 RC (2008-08-18 r46382) under linux I'm unaware of any motivation for constructing the above data structure, but if unlist is going to operate on it without error I would be surprised if that is the

Hi, I'm trying to modify this function.I want to remove the existing xaxis(the tick marks and the values below each tick) and make it dynamic so that i can choose whether i want the xaxis at the top or bottom but i cant seem to change that.can somebody help me? plot.Sample <- function(x,xlab=NULL,ylab=NULL,...){ sampletest <- is.Sample(x,argname="'x' ") if

Hello, I'm plotting an xyplot where a continuous var recorded every min is plotted on y, and time expressed as HH:MM:SS on x, as follows : xaxis=list(tick.number=12,rot=90) lst=list(x=xaxis) xyplot(upt$LOAD_1 ~ upt$TIME, data=upt, type=c('g','p', 'r'), scales=lst) On the x-axis, every time label is drawn and the label quickly become unreadable as they overlap on each

I need to make a fairly complex animated graphic and decided to use grid for it. A very simple example of what I need: ##============================================================================== library(grid) grid.newpage() pushViewport(plotViewport()) pushViewport(viewport(xscale = extendrange(c(0, 100)), yscale = extendrange(c(0, 100)))) grid.xaxis() grid.yaxis()

Hello R Users, I have two sets of values x <- c(7, 7 , 8, 9, 15, 17, 18) y <- c(7, 8, 9, 15, 17, 19, 20, 20, 25, 23, 22) I am able to create multi histogram using multhist(). But not able to control the 'xlim'. ie the xaxis is showing 7.5, 13, 18, 23 1st on what basis it is calculated 2nd I want it to be like 7 8 9 15 17 and so on Can any one help me With Regards Subhabrata

Hi all, how do I change the magnification of xaxis annotation? I need a smaller axis text size in some of my plots. I tried cex.axix=0.5 in plot(), but this doesn't work.

Dear friends. As promised ver 1.01 solved the former problem and now dates plot OK in windows. But. In the following code, "cex.axis"=0.5 works OK but "xaxp"=c(14620,14680,4) has seemingly no effect. The limits for xaxp was found from the default plot and inspecting par(). I need to put the date marks at specific points. Could I suppress them altogether and make a new xaxis

Dear All, Apologies for this simple question and thanks in advance for any help given. Suppose I wanted to plot 1 million observations and produce the command plot(rnorm(1000000)) The labels of the xaxis are 0, e+00 2 e+05 etc. These are clearly not very attractive (The plots are for a PhD. thesis). I would like the axes to be 0,2,4,6,8,10 with a *10^5 on the right hand side. Is there a

Hi! I'd like to plot things with axes going from the highest to the lowest value, so that e.g. high values on the xaxis are plotted to the left and low values to the right. Could anyone tell me how this is done? I couldn't find anything in the documentation. Thanks a lot! Silli
