Also asked, what does Cex mean in R?

cex. number indicating the amount by which plotting text and symbols should be scaled relative to the default.

One may also ask, how do you make a point transparent in R? Make transparent colors in R In addition, you set an alpha value (also 0–255), which sets the transparency (0 being fully transparent and 255 being “solid”). You also need to set the maximum color value, so that the command can relate your alpha value to a level of transparency.

Keeping this in view, what does Lwd mean in R?

line width for the points, defaults to the one for lines, or if that is not set, to par("lwd") . xjust. how the legend is to be justified relative to the legend x location. A value of 0 means left justified, 0.5 means centered and 1 means right justified.

How do I fill a plot point in R?

The following arguments can be used to change the color and the size of the points :

  1. col : color (code or name) to use for the points.
  2. bg : the background (or fill) color for the open plot symbols. It can be used only when pch = 21:25.
  3. cex : the size of pch symbols.
  4. lwd : the line width for the plotting symbols.

What is Ggplot in R?

The ggplot2 package, created by Hadley Wickham, offers a powerful graphics language for creating elegant and complex plots. Its popularity in the R community has exploded in recent years. There is a helper function called qplot() (for quick plot) that can hide much of this complexity when creating standard graphs.

What does Las mean in R?

par sets or adjusts plotting parameters. Here we consider the following three parameters: margin size (mar), axis label locations (mgp), and axis label orientation (las). las – A numeric value indicating the orientation of the tick mark labels and any other text added to a plot after its initialization.

What is plot in R?

The most used plotting function in R programming is the plot() function. It is a generic function, meaning, it has many methods which are called according to the type of object passed to plot() . In the simplest case, we can pass in a vector and we will get a scatter plot of magnitude vs index.

How do I increase font size in R plot?

To change the font size of text elements, use cex (short for character expansion ratio). The default value is 1. To reduce the text size, use a cex value of less than 1; to increase the text size, use a cex value greater than 1.

What is a legend on a graph?

The legend of a graph reflects the data displayed in the graph's Y-axis, also called the graph series. A graph legend generally appears as a box to the right or left of your graph. The box contains small samples of each color on the graph as well as a short description of what each color means.

How do you make a legend outside the plot in R?

The simplest way to plot a legend outside a figure in R is to:
  1. First step, make the outer margin at the bottom of the plot large:
  2. Second step, make the multi-panel figure (not shown)
  3. Third step: overlay the entire figure region with a new, single plot.
  4. Result:

How do I remove outliers in R?

There are no specific R functions to remove outliers . You will first have to find out what observations are outliers and then remove them , i.e. finding the first and third quartile (the hinges) and the interquartile range to define numerically the inner fences.

What is legend function r?

To add legends to plots in R, the R legend() function can be used. A simplified format of the function is : legend(x, y=NULL, legend, fill, col, bg) x and y : the x and y co-ordinates to be used to position the legend. legend : the text of the legend. fill : colors to use for filling the boxes beside the legend text.

How do you calculate Cronbach's alpha in R?

The Cronbach's alpha computed by cronbach. alpha() is defined as follows α=pp−1(1−∑pi=1σ2yiσ2x), where p is the number of items σ2x is the variance of the observed total test scores, and σ2yi is the variance of the ith item. The standardized Cronbach's alpha computed by cronbach.

What is Alpha ggplot2?

ggplot2 Quick Reference: alpha. Most geoms have an "alpha" parameter. Legal alpha values are any numbers from 0 (transparent) to 1 (opaque). The default alpha value usually is 1. The alpha can be set to a constant value or it can be mapped via a scale.

How do I make a scatter plot in R?

A scatter plot can be created using the function plot(x, y). The function lm() will be used to fit linear models between y and x. A regression line will be added on the plot using the function abline(), which takes the output of lm() as an argument. You can also add a smoothing line using the function loess().
