rescale

I need to reshape data.frame in R in one step . In short, change of values of objects (x1 to x6) is visible row by row (from 1990 to 1995): > tab1[1:10, ] # raw data see plot for tab1 id value year 1 x1 7 1990 2 x1 10 1991 3 x1 11 1992 4 x1 7 1993 5 x1 3 1994 6 x1 1 1995 7 x2 6 1990 8 x2 7 1991 9 x2 9 1992 10 x2 5 1993 I am able to do reshaping step by step, does anybody know how do it in one step? Original data Table 1 - see that minimal value from all timeseries is "0" Step1: Table 2 - rescale each timeseries that each would have minimal value equal "0". All times fall down on x-axes . Step2

R version 3.1.1 (2014-07-10) Platform: i386-w64-mingw32/i386 (32-bit) I am working on a heatmap with ggplot2() values from -1 to +1. I want to achieve that negative values have a bluish gradiend from darkblue(-1) to lightblue(-0.00000001) and the positive values a redish one from lightred(0.00000001) to darkred(1). Small values should not fade into white, as zeros should have white color and there shall be a visible contrast between 0 and a small value. NA values should be grey. I tried scale_fill_gradient2() and scale_fill_gradientn() also with rescale() . A similar topic has been discussed,

Recently discovered KineticJS as I've been trying to convert my Flash skills to HTML Canvas. It is an extremely impressive tool! Question: If I'm using a front-end like Bootstrap and I have a page with several divs that contain KineticJS-generated canvases, can I get those canvases to scale along with everything else on the page? Thanks much. ----- Due to character limit of comments, I'm replying in the OP. --------- Would you set it up so that there is a maximum size and then have it scale as when the browser is scaled? For example, in Actionscript I did this to track the size of the browser

I have an image which I resize: if((width != null) || (height != null)) { try{ // scale image on disk BufferedImage originalImage = ImageIO.read(file); int type = originalImage.getType() == 0? BufferedImage.TYPE_INT_ARGB : originalImage.getType(); BufferedImage resizeImageJpg = resizeImage(originalImage, type, 200, 200); ImageIO.write(resizeImageJpg, "jpg", file); } catch(IOException e) { System.out.println(e.getMessage()); } } This is how I resize the image: private static BufferedImage resizeImage(BufferedImage originalImage, int type, Integer img_width, Integer img_height) { BufferedImage

I'm writing a Qt application that needs to run on high-dpi Windows (192dpi instead of 96dpi). Unfortunately the Qt framework does not have support for high-dpi yet (at least on Windows), so my application and all its elements looks half the size it should. Is there any way to force/simulate automatic upscaling of such apps by Windows? Nejat Applications that use fixed coordinates and sizes will look small on high-DPI resolutions. Although even if using layouts there are some issues regarding element and font sizes and margins. Fortunately there is support for high-DPI displays since Qt 5.4 as
