Usually a radio scanner or a dedicated weather radio receiver is needed for listening, although in some locations a weather radio broadcast may be re-transmitted on an AM or FM broadcast station, on terrestrial television stations, or local public, educational, and government access (PEG) cable TV channels or during weather or other emergencies.
I'm trying to create a scatter plot using ggplot. The x value goes roughly from 0-20, and the y value goes from 0-~50. The data is raw so it's not nice and neat and I need to plot a curved line th...
The qr() function in R also performs the Gram-Schmidt process. The qr() function does not output the Q and R matrices, which must be found by calling qr.Q() and qr.R(), respectively, on the qr object.
The plot function will be faster for scatterplots where markers don't vary in size or color. Any or all of x, y, s, and c may be masked arrays, in which case all masks will be combined and only unmasked In addition to the above described arguments, this function can take a data keyword argument.
Reference. Plot basics. All ggplot2 plots begin with a call to ggplot(), supplying default data and aesthethic mappings, specified by aes(). A handful of layers are more easily specified with a stat_ function, drawing attention to the statistical transformation rather than the visual appearance.
Draw a scatter plot with possibility of several semantic groupings. The relationship between x and y can be shown for different subsets of the data using the hue, size, and style parameters. These parameters control what visual semantics are used to identify the different subsets.
Nov 06, 2009 · The first two arguments to the function are the name of objects that contain the x and y variables for the plot that is being created. Like many functions in R there is a data argument that can be used to specify a data frame to look in for the variables.
Key R function: geom_smooth() for adding smoothed conditional means / regression line. Key arguments: color, size and linetype: Change the line color, size and type. fill: Change the fill color of the confidence region. A simplified format of the function `geom_smooth(): geom_smooth(method="auto", se=TRUE, fullrange=FALSE, level=0.95)
