I am having a problem creating a scatterplot with error bars using gplot. This is only my second day using R so I am very much a newbie. My x-values (OD600) are: 0.00400000 0.01866667 0.04733333 0.08733333 0.22466667 0.42400000 0.82066667 1.39233333 1.61100000 My y-values (cellconc) are: 2e+06 5e+06 1e+07 2e+07 5e+07 1e+08 2e+08 5e+08 1e+09 And my standard deviations (stdev) are: 0.001154701

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!

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, 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", mapRegion="Europe", addLegend=FALSE) # ISO3 codes on

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,

I'm trying to draw an arrow with a curved shaft on the graph as a straight one looks messy on a detailed graph. I've looked in arrows but it doesn't seem to give an option. larrows doesn't look much more promising. I had a look in the archive and couldn't find anything. Any thoughts?

I have started using the circular package but it is not recognizing the function arrows.circular. I attempted to use the example provided in the circular manual. Here is the example code using the circular package: plot(rvonmises(10, circular(0), kappa=1)) arrows.circular(rvonmises(10, circular(0), kappa=1)) arrows.circular(rvonmises(10, circular(0), kappa=1), y=runif(10), col=2)

Hi, I would like to draw arrows in a classic 2D plot. Which package should I use? is there R base functions that do job? On google, I could not find any useful discussion about this topic, except a link to the function 'grid.arrows' of the grid package. My problem is I would like to draw arrows at the edge of circles drawn by the 'symbols' function. Maybe there is already a

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

Hello forum! As the subject indicates, I am trying to make a barplot and would like my column names to be in bold. Is this possible in R without having to make my column names in mtext? Any help would be much appreciated. The code I am using is as follows. par(mar=c(3,8,2,2)) par(adj=.5) par(font=2) par(oma=c(3,3,3,3)) par(xpd=TRUE) Blot<-matrix(c(25.2995, 0.7625, 25.6135, 36.5770,

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 origin is typically at

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!

Hi all, I am trying to do something simple, but which is deviling me. I want to add an up-arrow to the x-axis, pointing to a specific location on the axis. I want the arrow to be as large as possible. Here is where I'm at with my code: #this part if from the ?plot example: require(stats) plot(cars) lines(lowess(cars)) #I am trying to use mtext to add the arrow... but I don't know how

Since keystrokes were brought up, this 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

The result of > plot(c(-1,1),c(-1,1),type="n") > arrows(0,0,1,1) > arrows(0,0,0,0) is not what I expected. The first arrow is drawn correctly. The second does not collapse to a point but goes from (0,0) off to (-infinity,infinity). I guess something is divided by zero in the internal function.

Hello everyone, I have successfully made an error bar graph using the points() command with the arrows() command to maually add on the standard errors. However, one slightly annoying feature of using this method is that the points dont line up exactly with the arrows (if you look carefully the points are never perfectly in the centre of the arrow), even when you move the arrows around in an
