I created a plot with multiple lines using matplot: matplot(a, cbind(b,c,d,e), pch=1) where the arguments of cbind are functions of a, for example. b <- 2a+3 c <- 3a+2 and so forth. How do add the corresponding labels to the resulting lines?
30 Δεκ 2011 · Yes, use geom_text() to add text to your plot. Here is an example: library(ggplot2) qplot(mtcars$wt, mtcars$mpg, label=rownames(mtcars), geom="text") ggplot(mtcars, aes(x=wt, y=mpg, label=rownames(mtcars))) + geom_text(size=3)
Using geom_text_repel or geom_label_repel is the easiest way to have nicely-placed labels on a plot. It makes automatic (and random) decisions about label placement, so if exact control over where each label is placed, you should use annotate() or geom_text().
Putting labels on stacked bar graphs requires finding the cumulative sum for each stack. To do this, first make sure the data is sorted properly – if it isn’t, the cumulative sum might be calculated in the wrong order. We’ll use the arrange() function from the dplyr package.
Use the title( ) function to add labels to a plot. title(main ="main title", sub ="sub-title", . xlab ="x-axis label", ylab ="y-axis label") Powered By . Many other graphical parameters (such as text size, font, rotation, and color) can also be specified in the title( ) function. # Add a red title and a blue subtitle. Make x and y.
In R plots you can modify the Y and X axis labels, add and change the axes tick labels, the axis size and even set axis limits. R plot x and y labels By default, R will use the vector names of your plot as X and Y axes labels. However, you can change them with the xlab and ylab arguments. plot(x, y, xlab = "My X label", ylab = "My Y label")
