Other graphical parameters (such as line type, color, and width) can also be specified in the abline( ) function. # add solid horizontal lines at y=1,5,7 abline(h=c(1,5,7)) # add dashed blue verical lines at x = 1,3,5,7,9 abline(v=seq(1,10,2),lty=2,col="blue") Powe...
The output of the previously shown R code is shown in Table 2 – A matrix object that contains the row numbers for each column of our input matrix.Example 2: Apply row() Function to Return Matrix of Row LabelsThis example shows how to get the row labels (i.e. the row names) of a...
There’s another built-in ggplot labeling function calledgeom_label(), which is similar togeom_text()but adds a box around the text. The following code usinggeom_label()produces the graph shown below. ma_graph +geom_label(aes(label = Place, size =NULL), nudge_y =0.7) Sharon Machlis, ...
To specify the tick values, use the rticks function. If you do not specify enough labels for all the ticks values, MATLAB® uses the labels followed by empty character vectors for the remaining ticks. If you specify the tick labels as a categorical array, MATLAB uses the values in the ...
It's somehow amazing to me that the option for slanted or rotated axes labels is not an option within the basic plot() or axis() functions in R. The advantage is mainly in saving plot area space when long labels are needed (rather than as a means...

In Example 3, I’ll explain how to specify labels only for some points that fall into a specific range. For this, we have to modify our label column using theifelse function: ggplot(data, aes(x, y, label=label))+# ggplot2 with some labelsgeom_point()+geom_text(aes(label=ifelse(...
It is easy to store labels as variable attributes in R but most R functions cannot use them or even drop them. expss package integrates value labels support into base R functions and into functions from other packages. Every function which internally converts variable to factor will utilize ...

In base R, we can rotate the axis label horizontally, vertically, or perpendicular to the axis. Let’s first show the plot for which we will rotate labels, and after that, each method is demonstrated in the following. Example Code: ...
