Help creating a scatterplot with errorbars using gplot
...d deviations (stdev) are: 0.001154701 0.003000000 0.002081666 0.009865766 0.015716234 0.040253364 0.017691806 0.013868429 0.007234178 I use the command: plotCI(OD600, cellconc, uiw=stdev) And I receive a graph that looks correct but without any error bars. I also receive these warnings: 1: In arrows(...) : zero-length arrow is of indeterminate angle and so skipped 2: In arrows(...) : zero-length arrow is of indeterminate angle and so skipped 3: In arrows(...) : zero-length arrow is of indeterminate angle and so skipped 4: In arrows(...) : zero-length arrow is of indeterminate angle and so ski...

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! Sincerely, Milu On Tue, Apr 12, 2016 at 1:15 PM, Jim Lemon <drjimlemon at gmail.com> wrote: > Hi Milu, > There is a two-heade...

plotting arrows with different colors and varying head size
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 lengt...

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.

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", mapRegi...

Add an arrow to a plot
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 will say: An arrow? Which width?size? I first need to see how it looks and if it is posible. Many thanks in...

Hi all, I've been using the arrows() function in plots a lot, but I'm not happy with the appearance of the arrow heads. I understand that arrows () doesn't offer more sophisticated arrowhead shapes like e.g. a filled triangle, possibly with choice of angle at the point. Does anyone know an easy way to achieve this?...

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!

How to scale arrows to approximately fill a plot region?
In a variety of graphic applications, I plot some data, together with arrows representing variables or linear transformations of variables as vectors in the same space, as in a biplot. In my applications, the scale of the arrows is arbitrary -- all that matters is relative length. I'd like to blow them up or shrink them to fit the available space in the plot. The o...

Hi Milu, I just realized that by "the bottom of the map" you may mean "beneath the map", in which case you should use: par(xpd=TRUE) arrows(...) par(xpd=FALSE) Jim On Mon, Apr 11, 2016 at 11:50 PM, Miluji Sb <milujisb at gmail.com> wrote: > Dear David, > > Thank you very much for your replies!

Arrow key feature request
...is seems like a reasonable time to make the following seemingly simple-to-implement feature request: Navigating a multi-level menu structure seems to require use of UP/DOWN/ENTER/ESC. It would be easier to quickly search/navigate if it could be done with fingers stationed on the arrow keys so that the eyes can stay focused on the screen. Current (disliked-by-me) behavior: LEFT ARROW: Jump to top menu entry (same as HOME and PAGE UP) RIGHT ARROW: Jump to bottom menu entry (same as END and PAGE DOWN) Preferred (requested) behavior: LEFT ARROW: Return to previous menu (...

Redundancy canonical analysis plot problem in 3D using VEGAN
...es " from RDA results in 3D plot like i can in 2D plot. With the code i used , i get errors like ; ERROR dans t\$sites : \$ operator is invalid for atomic vectors, Erreur dans match.arg (display, items) : 'arg' should be one of ?xyz.convert?, ?points3d?, ?plane3d?, ?box3d?, ?points?, ?arrows? I saw that I can use other functions, but it is impossible to extract the 3D scores ( and add species to 3d plot ), Other fonctions works but, add elements in a 2D space. How can I add the "species scores" (sites and arrows are added correctly) to the 3D plot as with the 2D plot. Th...

persp(), scatterplot3d(), "..." argument
Hello list. I very often need 3d scatterplots, and use scatterplot3D quite a lot. I am trying to modify persp() to plot scatterplots, and make use of the theta and phi arguments that persp() offers. I am having some difficulty passing the correct arguments to persp(). Here is my function so far. Much of it is copied from the persp() manpage. points3d <- function(x,y,z,

Autocompleter - up arrow moves cursor to start of input box
When using the autocompleter and scrolling through options, if you press the up arrow key the input field cursor moves backward. Some of my users have reported that they find this very distracting. Does anyone know why this happens, or where in the code I could fix it? Steps to recreate: 1. Go to http://demo.script.aculo.us/ajax/autocompleter 2. Type in a letter (or...
