gplots

问题 In an R markdown report rendered to both PDF and HTML, I would like to colorize text with different transparencies. For example, I would like to use the same orange with 3 different alpha values (0.3, 0.6, 1.0). Nicholas Hamilton provides a function to color text regardless of the output format (PDF/latex or HTML). An updated MWE of the fct. was provided by Mark Neal. To work with transparent colors, the colFmt() function needs to be adapted somehow as far as I see. What I tried gplots:

问题 I would like to make a plot using R studio similar to the one below (created in Arc Map) I have tried the following code: # data processing library(ggplot2) # spatial library(raster) library(rasterVis) library(rgdal) # test <- raster(paste(datafold,'oregon_masked_tmean_2013_12.tif',sep="")) # read the temperature raster OR<-readOGR(dsn=ORpath, layer="Oregon_10N") # read the Oregon state boundary shapefile gplot(test) + geom_tile(aes(fill=factor(value),alpha=0.8)) + geom_polygon(data=OR, aes(x

问题 I'd like to plot a set of thumbnail images as points on a scatterplot. I've started with the answer code located here but they repeat the same thumbnail throughout the plot, whereas I have a list of images. xy <- data.frame(x=runif(337, 0, 100), y=runif(337, 0, 100)) imgfiles <- list.files(getwd(),pattern="*-scaled.png") img <- lapply( imgfiles,function(x) readPNG(x) ) thumbnails <- function(x, y, images, width = 0.1*diff(range(x)), height = 0.1*diff(range(y))){ images <- replicate(length(x),

问题 I have done a Heat Map using the function heatmap.2 of gplots in R, but I don't have an idea of how to coloring the branches and tick labels per groups (Eg. if I cut the tree to have four gruops like in my second figure). I have checked that it is possible to color the dendrogram alone using dendextend package. Also there is a heatmap here: selecting number of leaf nodes of dendrogram in heatmap.2 in R with a colored dendrogram, but I can't implement it in my example. Somebody can help me

问题 I'm visualizing a data set with the heatmap.2 function from the gplots package in R. Basically I'm performing a hierarchical clustering analysis on the original data, while forcing the heatmap to display a limited version of the data (between -3 and +3) to limit the effect of outliers on the appearance of the heatmap, while still retaining the original clustering. When I use the full data set ( fullmousedatamat ), it works just fine. However, when I use a partial data set (
