heatmap.2 and color key tick marks

阅读更多关于 heatmap.2 and color key tick marks

问题 I've made a heatmap in R using heatmap.2 and the only thing I can't figure out is how to control the presence and labeling of tick marks on the color key. I have an example below. What I would like to do is have tick marks at the beginning and end of the color key to indicate the range of values (in this case 0-1), rather than 6 tick marks with labels at 0, 0.4 and 0.8. I'm sure there is a simple way to control this but I can't seem to find it. library('gplots') data <- c(0, 0.1, 0.1, 0.2, 0

Java Opengl: Discarding Texture Background with Shaders

问题 I'm trying to follow this tutorial to remove the background color of texture with a shader. https://www.opengl.org/sdk/docs/tutorials/ClockworkCoders/discard.php Everything is running correctly, I copied the shader code directly from the tutorial, however the fragment shader is throwing several errors. sampler2D myTexture; varying vec2 vTexCoord; void main (void) { vec4 color = texture2D(myTexture, vTexCoord); if (color.rgb == vec3(1.0,0.0,0.0)) discard; gl_FragColor = color; } ERROR: 0:3:

I read the heatmap.2 help manual a couple of times now, and also in various online tutorials I didn't read about a way to move the color key to a different position. Now, I am wondering if it is even possible? The color key is in the upper left corner by default if you are using the heatmap.2 function from the gplots package. The position of each element in the heatmap.2 plot can be controlled using the lmat , lhei and lwid parameters. These are passed by heatmap.2 to the layout command as: layout(mat = lmat, widths = lwid, heights = lhei) lmat is a matrix describing how the screen is to be
