Dateticks
Hello. I am having the worst time converting x-axis date ticks to real dates. I have tried several suggestions in online help tips and books to no avail. For example, the x-axis has 0, 50, 100, etc, and I want it to have "6/17/03", "8/6/03" etc. See attached (sample). Can anybody help me with this. Here's my code: ts.plot(date.attackmode.table[,1],

overlay points on plot
Dear R-help list, I'm trying to overlay a number of data objects in a plot. Following an earlier example on the list I've created an empty plot as follows > xlim <- range(as.numeric(c("0","10000"))) > ylim <- range(as.numeric(c("0","25")) ) > plot(NA, xlim=xlim, ylim=ylim, xlab="distance", ylab="semivariance")

matlab norm(h) command in R: sqrt(sum(h^2)) - use in an expression
Hi in matlab I defined a function (double gamma, parameters at the end of this mail) as h(i)=((t/d1)^a1)*exp(-(t-d1)/b1)-c*((t/d2)^a2)*exp(-(t-d2)/b2); h=h/norm(h); I do know that norm() in matlab is equal to: sqrt(sum(x^2)) in R so in R I do it like: #function (double gamama) h <- expression((t/d1)^a1*exp(-(t-d1)/b1)-c*(t/d2)^a2*exp(-(t-d2)/b2)) # plot it t <- seq(0, 20000,

Rounding fractional numbers to nearest fraction
Hi all, I've got a matrix of fractional data that is all positive and greater than zero that I would like to "loosely" classify, for lack of a better word. It looks something like this : 1.07 1.11 1.27 1.59 0.97 0.76 2.23 0.98 0.71 0.88 1.19 1.02 What I'm looking for is a way to round these numbers to the nearest 0.25, i.e. the above matrix would be

Error with repeat lines() in function
I have a function that does some plotting. I then add lines to the plot. If executed one line at a time, there is not a problem. If I execute the function, though, I get: Error in ans[[1]] : subscript out of bounds This always occurs after the second lines command, and doesn't happen with all of my data points (some do not have errors). Any ideas? Thanks, Sean

overriding "summary.default" or "summary.data.frame". How?
I suppose everybody who makes a package for the first time thinks "I can change anything!" and then runs into this same question. Has anybody written out information on how a package can override functions in R base in the R 2.14 (mandatory NAMESPACE era)? Suppose I want to alphabetize variables in a summary.data.frame, or return the standard deviation with the mean in summary output.

Now I would like to write a short program to draw one graph as follow for each level of stname but I would like also to draw each time 12 graphs for the 12 levels of stname in the same

bwplot puts the bars in the wrong place
Dear R-Help, With the attached data set, I am still getting incorrect bwplots > xyplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf) # Is correct > bwplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf, horizontal=FALSE) # Puts the boxes on the wrong x-axis values # look especially at 0 and 3. How do I fix this? What is happening? Thanks, Jim Rome

Problem reading a PDF output
I generated a PDF output file of 10 plots. When I try to view it with Adobe reader (R4 & R5), it will lockup the reader (it is consuming 100% of the CPU) after presenting the 4th plot. I can generate the plots just fine in Windows and as a postscript file reading it with GSview. Is there anyway to tell what might be wrong with the PDF output? The file is 890KB in size if anyone would like

Avoiding a Loop?
Dear R-Helpers, I have a matrix where the first column is known. The second column is the result of multiplying this first column with a constant "const". The third column is the result of multiplying the second column with "const"..... So far, I did it like this (as a simplified example): nr.of.columns <- 4 myconstant <- 27.5 mymatrix <- matrix(numeric(0), nrow=5,

Resolution issue with exporting plots from R and write tables in Latex code for producing pdf document
Dear R users I am trying to exporting plots from R to an external folder, or to the working directory, but the resolution of plots (pdf file) largely reduced. Any way I can get same quality as my original plots?? e.g. I tested the plotting part using one example and obtained pretty good (/readable) quality for each plot in the (4*4) multiple graph.

initial points for arms in package HI
Dear R-users I have a problem choosing initial points for the function arms() in the package HI I intend to implement a Gibbs sampler and one of my conditional distributions is nonstandard and not logconcave. Therefore I'd like to use arms. But there seem to be a strong influence of the initial point y.start. To show the effect I constructed a demonstration example. It is reproducible
