Hello all, I'm having a bit of a problem with x and y axis labels. Two things: first, if I want to create a plot with, plot.new() plot.window(.....) axis(1) axis(2) lines(...) points(...) [etc.] ... where do I introduce the xlab=... and ylab=... commands? I attempted this in plot.window() but no labels showed up. Second, here's a bit of real code...

Hello, How to use the function plot to produce graphs as Matlab? example in Matlab: a = [1,2,5,3,6,8,1,7]; b = [1,7,2,9,2,3,4,5]; plot(a,'b') hold plot(b,'r') How to make the same in R-package ? I am trying something thus: a <- c(1,2,5,3,6,8,1,7) c(1,7,2,9,2,3,4,5) -> b a;b plot(a,t="l",col="blue") plot(b,t="l",col="red")

The Blue Book allows the 'type' argument to be used in matpoints and matlines. matlines(x, y, type="l", lty=1:5, pch=, col=1:4) R-1.0.0 does not. Thus, type="h", "b", must be invoked thru matplot( x, y, type = "h", add=TRUE) For the sake of consistency with S, it would be nice to have matlines defined as: "matlines" <-

Based on reading 'rgb' documentation, I would have thought the following would have produced identical results. Can someone explain how to make this happen? I need to be able to specify an array of rgb values for the 'col' parameter. colnames.col <- c("black", "red", "blue", "green") colnames.rgb <- apply(as.matrix(colnames.col), 1,

Can you provide an example? ????? The standard matplot application that concerns me is with matplot(x, y, ...) where x has class Date or

I'm using (Linux version) xfig() within a function and then simple matplot() and matline() plots. Although I do not define any bg or fg default color, sometimes all lines in the final fig file are green. The same code works as (I) expected if I use x11() or pdf(). This is what I'm doing: I open 2 devs: xfig() dev.set(2) layout(mat1) xfig() dev.set(3)

Hello, I am trying to port one of my plotting S+ functions to R and I am having difficulties!!! I am including here only the troublesome code! I first produce a barplot, saving the positions of the bar's centers. par(mar = c(6.1, 5.1, 4.1, 4.1), mgp = c(3, 3.0, 0)) ticks.loc <- barplot(sum.of.weights, col = 5, xlab = "", ylab = "", axes =

Dear All, I created a script to calculate averages - two groups: "parcel" and "date" - and, based on these averages, make a graph. The problem is that 'R' does not recognize the first column even if I try to insert one. A brief example Raw data: Data <- sample(1:100, 30, replace = FALSE, prob = NULL) Date <-

Is there a way to create Bollinger Bands without having to loop on the observations of a time serie? Any help appreciated Thanks

I am new to R and have a problem that I haven't been able to find the answer to in the guides or online. I have multiple datasets, D1, D2, D3, D4, D5, D6, D7 and D8, and I would like to produce two plots side by side using mfrow.  The first plot should contain data from D1-D4, the second should contain D5-D8. I can plot these separately using the code, par(mfrow=c(1,1))

Hello, All: ????? Roughly a decade ago, I added "matplot.Date" and "matplot.POSIXct" to the "fda" package, so we could get reasonable labeling of the horizontal axis when "x" was class "Date" or "POSIXct".? I also added a local version of "matplot.default" that just changes the defaults for "xlab" and

Hi all, I'm still a bit new to R and I'm trying to figure something out. I have the solution but the solution is what a C programmer would do :-) and I was wondering if someone could tell me the R way of doing it... What I have is a vector x of length |x|. And a matrix y of size m rows and n columns where n = |x|. I want to plot m * n points on a graph so that the x-coordinates

I'm slowly moving my statistical analysis from Matlab to R, and find myself missing two features: a) How do I mimic Matlab's 'hold on'? (I want to show several plots together, when I type two plots one after the other the second overwrites the first) b) How do I mimic Matlab's 'axis'? (after drawing my plots I want to zoom on specific parts- for example, x=0:5,

Anyone who is interested in using optimal colour palettes should look at the work of Cindy Brewer: www.colorbrewer.org I have written code to use her colour schemes in R. It is included below. Perhaps someone may find this interesting enough to work into a package. Included also is a function showpalette, which was posted here a while back. I don't remember who wrote it. I have copied all

Dear R-Users I have 2 questions: Firstly, If I create a matplot and legend for multiple vectors and then tag another vector on using matlines (e.g. a 'total' of all vectors), is there anyway to add the new line to the legend without recreating it? I have created the plot this way because I would like to define the lty and lwd for the 'total' vector so that it can be

Dear R help, This seems to be a commonly asked question and I am able to run examples that have been proposed, but I can't seems to get this to work with my own data. Reproducible code is below. Thank you in advance for any help you can provide. The main problem is that I can not get the confidence lines to plot correctly. The secondary problem is that predict is not able to find my object

Dear R-users, I am using R version 2.10.1 under windows. In a barplot, I want to mark one of the bars with a special border color. For example: barplot(c(3, 7, 11), border = c(NA, "red", NA)) But how to do this when the bars are stacked? for example: barplot(matrix(1:6, ncol=3)) # border of second bar (i.e. the one with total height = 7) should be red again, I try: barplot(matrix(1:6,
