I would like to produce a chart that looks like a Gantt chart (or shingle plot), but instead of tasks you have variable names and instead of start and finish dates you have an upper and lower numeric value. If that makes sense, is there an obvious way of doing this. Thanks, Graham

Does anyone know if there is a package or other method of reading Genstat files directly into R. Genstat isn't listed in the foreign package. Many thanks, Graham [[alternative HTML version deleted]]

I'm new to R and some what new to the world of stats. I got frustrated with excel and found R. Enough of that already.

Hello Jim, Thanks again. I am getting the two-headed arrow but I cannot seem to get the coordinates right for the arrow to appear beneath the map. These coordinates puts the arrow on the left hand side. Thanks again!

Hi Everyone, I am trying to use lmFit function; however, i cannot find it function anywhere. I have been trying to find the function in Bioconductor and elsewhere. I re-install bioconductor source, update package and update R as well. no luck Is there a command in R where i can just type, and it will download it for me? -- View this message in context:

hello, ladyes and gentlemans. check this: means<-c(4,6,8) stand.error<-c(0.1,0.3,0.5) now i've strongly tryed to scatterplot the means(y-axis),by showing their sd with the arrow(..,code=3,angle=90) function. The problem is that my x-axis has categorical values (say, factor(x)), and the arrows() can't recognize them as right coordinates. ????? thank you all in advance B.F. insubria

Hi Milu, My fault here. As I don't have the data to make the map and try out my suggestions I mixed up the x and y coordinates. Try this: par(xpd=TRUE) arrows(-19.75966,53,33.60000,53,code=3) par(xpd=FALSE) Jim On Tue, Apr 12, 2016 at 10:11 PM, Miluji Sb <milujisb at gmail.com> wrote: > Hello Jim, > > Thanks again.

I have a data set called GQ1, which has 20 variables one of which is a factor called Status at thre levels "Expert", "Ecol" and "Stake" I have managed to evaluate some of the data split by status using commands like: summary (Max[Status=="Ecol"]) BUT how do I produce asummary for Ecol and Expert combined, the only example I can find suggsts I could use

arrows() seems to hang when either x or y scale of the plot is logarithmic and the arrows requested go beyond the plot (by more than a certain amount). I didn't go into C code to find it, but here's a function that exercises the bug a bit ... arrow.bug2 <- function(y0=1,y1=10,log="y") { plot(c(0.1,1),c(1,10),log=log) arrows(x0=0.5, y0=y0, x1=0.5,

Dear R developers, I want to draw an arrow in a figure with lty=2. The lty argument also affects the edge of the arrow, which is unfortunate. Feature or bug? Is there some way to draw an arrow with intact edge, still with lty=2? Example code: plot(1:10) arrows(4, 5, 6, 7, lty=2) Best wishes, Matthias --

Dear list, I would like to plot arrows with different colors according to arrow length, and also (if possible) with head size proportional to arrow length. The idea is to make a quiver-like plot of matlab with wind speed data. So far, I´ve been able to use different colors, but I need to find a more efficient way to recode arrow length intervals into colors. On the contrary, I can't define

Hi Milu, There is a two-headed arrow on the image you sent, and it seems to be where you specified. Did you want it beneath the map, as: par(xpd=TRUE) arrows(-22,54.75,-22,74,code=3) par(xpd=FALSE) Jim On Tue, Apr 12, 2016 at 7:58 PM, Miluji Sb <milujisb at gmail.com> wrote: > Dear Jim, > > Thanks again!

Hi I want to plot an x,y plot something like an scatter plot. I always have the same doubt, were is the last point of my file? Imagine it is a time series so I want the last point to indicate with an arrow (but athomatically if posible). Someone knows if it is posible? Could it be posible to add additional arrows (with a small square with text?) I hope you can comprehead me? I suppose you

My data: I have raw data points that form a logit style curve as if they were a time series. Which is to say they form 3 distinct lines with 3 distinct slopes in backwards z pattern. A certain class of my data looks essentially flat to the eye with marginal oscillation. What is important to me is the x value at which the state change is occurring, in other words, the break point Use of

Dear Jim, Thanks again! I do want the arrows at the bottom (beneath the map). This is what I am doing: # Draw the map eps_europe <- mapCountryData(n, nameColumnToPlot="eps_score", mapTitle="EPS Score - Europe",colourPalette=colourPalette, catMethod="fixedWidth", missingCountryCol = "white", mapRegion="Europe", addLegend=FALSE) # ISO3 codes on

I have started using biplot() (with R1.3.0 on Windows) and have become very frustrated. As far as I can see, I follow the directions but either it doesn't do what I want it to do, it gives fairly arcane error messages or both. All I want to do is plot two separate data sets to see how different they are from each other with respect to two metrics that are represented by the two axes. My

x=rmvnorm(2000, rep(0, 6), diag(c(5, rep(1,5)))) x=scale(x, center=T, scale=F) pc <- princomp(x) biplot(pc) There are a bunch of red arrows plotted, what do they mean? I knew that the first arrow labelled with "Var1" should be pointing the most varying direction of the data-set (if we think them as 2000 data points, each being a vector of size 6). I also read from

Greetings, I would like to add 3D arrows (i.e. arrow-headed vectors linking X1Y1Z1 to X2,Y2,Z2) to a 3D plot; ideally the sort of plot that can be rotated interactively. Is this possible using plot3d, or another 3d plotter in R? While it is easy to draw segments in plot3d (e.g. below), I haven't figured out how to add arrow heads, or to create 3d arrows from scratch. ##two headless

Am doing some vector plots with the arrows() function. Works well. But what I need to do is supply an arrow for scaling for the reader. I need to plot an arrow of some known magnitude somewhere on the page (preferably outside the bounds of the plot, so that it can be seen clearly) with some text underneath it that says, for instance, "10 kg-m/sec". Any ideas? Thanks.
