Dear colleagues, I have an image which I can display in the greyscale using image. On this image, for some pixels, which I know, I want to display their activity based on a third measure. One way to do that would be to color these differently, and use an opacity measure to display the third measure. An example of what I am trying to do is at:

I pushed out some changes to gwd that makes it possible to properly set an overall opacity value for any metacity theme. Making the complete decorations translucent can look bad with some themes. However, I've made it possible to have the opacity fade from opaque to the selected opacity value in a similar way to how the built-in decorations look. This usually looks a lot better. I'll add

Hello list, I would like to try indexing data in a database table. While I got dbi2omega to work and print the data, I am still not sure how it all works together. What should be done to the output from dbi2omega? If for example I have a table with 5 fields 2 of which I would like to index, like so: (id primary key, title varchar(100), name varchar(100), description

Hi, This patch adds appropriate limits (1-100) to opacity_values in core options. Minimum is 1 to be consistent with the opacity changing action and because it doesn't make sense to have an invisible window that is still there.

hi, I made a small a patch for gtk-window-decorator which define default border alpha to zero when it use metacity theme. That allows while playing with the alpha attributes of the metacity themes to have transparent borders. here too the modified ?Human Ubuntu? theme and a screenshot to show the result. ps: sorry for my bad english -------------- next part -------------- A non-text attachment

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This patch uses the same hacks listed in the "[PATCHES] Fixes for java apps and firefox in scale, switcher and wobbly" message to apply the transparency to the right windows; I don't think it will be merged, but I'm posting it here just as example for other users/packagers; however it can be disabled only setting the default

The drag&drop effect in scriptaculous makes my div dissapear in IE. I take it this is because I have a filter on the div to get alpha transparency on the pngs, and this is cancelled out by the opacity setting, yet it says this was fixed in scriptaculous. JavaScript for png filtering at bottom. The div becomes visible again (or rather, the images comes back) when dragging is ended. Any

Hey everyone, I have a series of thumbnails that have a loading overlay placed over them when they''re clicked on. The overlay is set to an opacity of .7.. .The onclick code looks basically does this: var loading = document.createElement(''div''); loading.id = ''loading_image''; $(loading).addClassName(''thumb_loading'');

Dear List, I want to use transparency in R to represent downweighting of observations based on clusters (repeated observations in a dataset). Some clusters will have identical covariate values in a parameter space -- in the 2D x,y case, these represent a bunch of semi-tranparent dots in the same place. I'd like these overlapping dots to be completely opaque. In other cases, the

Hola Javier, tu idea me hubiera solucionado el problema si hubiera estado usando plot() para hacer el grafico, pero como estoy forzado a usar xYplot() del a libreria Hmisc, me arroja un error diciendo que aun no uso plot() ... alguna otra idea si estoy usando Hmisc o lattice ? gracias, eric.

The abline function can be used to draw the regression line when one passes the lm object as an argument. However, if it's an intercept-only model, it appears to use the intercept as the slope of the abline: mod <- lm(dist ~ 1, data = cars) plot(dist ~ speed, data = cars) abline(reg = mod) # nothing appears This behaves as documented, but might catch someone. Would it be an improvement

Dear All, I am wondering on how to use the abline.xyplot with xyplot such that I will have different vertical lines for each panel. More sepcifically, suppose that the xyplot generates 4 panels defined by the combination of two binary variables: X_1 and X_2. i.e. xyplot(Y ~ Z | X_1*X_2, data = df) I want something like: abline(v = 5) if X_1=0 and X_2 = 0 abline(v =

Dear List: I am working to generate graphs for individual students that will be created through a series of loops in Sweave. Before doing so, I am still trying to design the graph. The code for creating the barplot is below with some sample datapoints just made up for now. Ultimately, this chart will take data from an lme object using longitudinal student data. So, the dots represent the

Hi folks, I'm using R 2.5.0 under ESS under Windows XP. (This also happens using the Rgui application.) I'm trying to add lines to a plot originally made with "boxplot", but the lines appear in the wrong place. Below is a script that illustrates the problem # boxablinetest.R - script to show problem with abline on box plot x <- c( 2, 2, 2, 3, 3, 3, 4, 4, 4) y

Hello there, I have some data I want to plot together with a best-fit line. (see MWE below) The points from the first plot does appear as expected, but the abline does not appear, no matter what I change. I removed the log parameter before, but the abline is a very steep line around the origin. I really want to keep the logarithmic scale, plus a working abline. Can someone help me with that?

All, I'm trying to truncate some lines that are added to an xyplot via panel.abline to allow additional space for inserted text. According to ?panel.abline it seems like "from" and "to" will do the trick but it does not work for the sample code below. Any hints much appreciated. Cheers, David x = seq(1,8) y.1 = .6*x + 3.5 + rnorm(8, 0, .5); y.2 = .4*x + 1 + rnorm(8,0,

Dear R users, please can you help me understand the behaviour of abline using function lm. I'm trying to learn linearity over groups. So I make three groups with 10 values each: test=data.frame(cbind( l=c(rnorm(10,0,30),rnorm(10,100,30),rnorm(10,200,30)), t = c(rep(0,10), rep(1,10), rep(2,10)) )) when I do: plot(test$l~test$t) abline(lm(test$l~test$t)) the abline is a straight line

The result of the code shown below is posted at the following URL: http://n2.nabble.com/Trying-to-properly-label-abline-td2524629.html I would like to figure out a better way to label the horizontal abline. I tried multiplying the text y position by a scale, but this didn't always put the text in a useful position. I guess I am curious if there is a preferred procedure for labeling the

Hi I just realized that when I use linear regression to draw a line through my data points with something like the following: abline(lm(y ~ x)) the length of the line is infinite, i.e., the line goes beyond the smallest and the largest data values. This seems not very right to me (not to mention it looks unaesthetic). I do not mean to imply that the straight-line behavior of my system is
