error: geom_density requires the following missing aesthetics: y
A geom_density() function can be used to plot y values based on their x value. In the standard case, no aesthetics are required. The second case requires a stat identity; the function is intended for precalculated values. It’s possible to mix the two cases, but you’ll receive an error message if you do.
Geom_density_2d() is a function that plots contour lines in two dimensions, and calculates the joint distribution of two variables. It also displays a histogram, which is a count statistic multiplied by the number of points. This can be used in stacked density plots. The following error messages may occur. These messages are a result of the Geom_density function being incompatible with the underlying data.
To avoid an error, specify x and y values separately. The geom_density function assumes that groups are equal and then computes proportions between groups. The following code will produce the stacked bar chart the user intends. If y values aren’t equal, normalize the heights of the bars so that they appear side by side.
When applying an aesthetic to a geom, it is important to specify the proper values for x and y. Otherwise, an error will occur. If the aesthetics are not correctly specified, the resulting plot may not have a good appearance. Geom_density requires the following missing aesthetics: y, x, and y. These options are important for plotting a map.
This function divides a plot into a grid and colors each bin by the number of observations. You can also plot multiple variables at once. For example, plot life expectancy versus per capita GDP. With geom_bin2d(), you can plot life expectancy versus per capita GDP. You can also plot y versus x. If you want to plot the two at once, geom_density requires the following missing aesthetics: y, x, and y.
Geom_density is an important statistical tool for spatial analysis. If the aesthetics were properly specified, this method would produce a plot with minimal jitter and with no visible jitter. By default, geom_density requires x, y, and y aesthetics. The missing aesthetics make the plot look great! Just make sure to choose the right one for your map!
