Hi, I would like to combine multiple xyplots into a single, multipanel display. Using R 3.0.1 in Ubuntu, I have used c() from latticeExtra to combine three plots, but the x-axis for two plots are on a log scale and the other is on a normal scale. I also have included equispace.log=FALSE to clean up the tick labels. However, when I try all of these, the x-axis scale of the first panel is used for all three. How do I keep different scales for the different panels? Here is an example: library(lattice) library(latticeExtra) response <- c(76, 14, 15, 44, 26, 19, 74, 123...

Dear all, I got a couple of warnings using panel.levelplot.raster, In panel.levelplot.raster(..., interpolate = TRUE) : 'y' values are not equispaced; output will be wrong although I was quite sure my data were equally spaced (indeed, I created them with seq()). A closer look at the source code reveals that the function tests for exact uniformity in grid spacing, if (length(unique(diff(uy))) != 1) warning("'x' values...

Dear users, I am trying to export polygons from Arcmap into Spatstat to run some simulations using functions available in Spatstat package. One particular area to be exported is formed by a number of polygons defining the external boundaries of the area (as a groups of islands) and a number of polygons inside the previous ones, as ?holes? not to be considered as part of the area. I have

...details{ The function \code{ts} is used to create time-series objects. These - are vector or matrices with class of \code{"ts"} (and additional + are vectors or matrices with class of \code{"ts"} (and additional attributes) which represent data which has been sampled at equispaced points in time. In the matrix case, each column of the matrix \code{data} is assumed to contain a single (univariate) time series.

Dear R users, I want to plot a one variable continuous function f(x) vs x, x=[0,1]. Say for example: f(x)= x^2. Now, using the command plot(f~x) I will get a curve where the range of x-axis is [0,1] with all equispaced label. But, I need something else, and that is: my curve will be such that 80% on x-axis the range would be [0,0.5] and the rest 20% would contain [0.5,1]. Let me draw informally here. Say, the line below is my x-axis in graph and my plotting points are like: _________________________...

I have an irregular time series in a Zoo object, and I've been unable to find any way to do an FFT on it. More precisely, I'd like to do an NFFT (non-equispaced / non-uniform time FFT) on the data. The data is timestamped samples from a cheap self-logging accelerometer. The data is weakly regular, with the following characteristics: - short gaps every ~20ms - large gaps every ~200ms - jitter/noise in the timestamp The gaps cover ~10% of the acquisiti...

Dear S-PLUS/R users: Do you know any default function or a user contributed function that can draw an ellipse with given axes and origin? Thanks for any help.

...posed to be unrelated. I have plotted them and that assumption does not appear to be valid. http://metrak.com/tmp/sevents.png is a plot showing three sets of events over time. For the purpose of this exercise, the Y value is irrelevant. The series are not sampled at the same time and are not equispaced (just events in a log file). The plot is already pretty convincing but requires a human-in-the-loop to zoom in on "hot" areas and then visually interpret the result. I want to calculate some index of the events' temporal relationship. I think the question I am trying to ask is...

Hello again, First I want to thank all the people who answered my question about line width in graphs. I promise I will learn the 'par' help page by heart for the end of the month ! I now want to trace some ellipses to emphasize groups of data. I found how to trace circles with 'symbols()', but no ellipse. I'm planning on writing my own function based on

Hi All. I'm trying to run nlsList an getting an error that makes no sense to me. I have accuracy and reaction time data over many trials for each person (id) When I use nlsList code that is virtually identical to the example in the doc file I get the following error. I've tried everything I could think of and can't get around it. Any ideas what I'm doing wrong? **************

Sorry this is my fault. I suggested this code because the previous version of [.ts<- did not allow you to subscript time series at all without unclassing them. The current version at least tries to preserve time series objects. I think what we really need...

I have a class "tframe" with more specific classes indicating how time is being represented, such as > class(tframe(data)) [1] "ts" "tframe" but now "[.ts" produces warning messages > tframe(data)[2] Warning: Not returning a time series object [1] 2006.25 Even my simplest tests produce hundreds of lines of warnings, so I've commented out

1) There's a curious asymmetry between points and lines, in that you can do lines(...,type='p') but not points(...,type='l') (and more importantly, not points(..., type='b'), which probably *could* arise in real work) This isn't deliberate, is it? 2) Did I remember to report the adverse effect of having plot(x,y) coerce its argument to numeric? Several of my
