Hace 6 días · 其中，ggplot2是一个功能强大的R语言可视化包，提供了丰富的功能和灵活的图形定制选项。在这篇文章中，我将介绍如何使用ggplot2的geom_ribbon函数向图表中添加置信度带，以帮助读者更好地理解数据。 首先，我们需要载入所需的包，并准备一些演示数据。
16 de may. de 2024 · Many of these ways are absolutely equivalent. Using stat_density(geom = "line") is identical to using geom_line(stat = "density").Note that for layer(), you need to provide the "position" argument as well. To give geoms as a string, take the function name, and remove the geom_ prefix, such that geom_point becomes "point".. Some of the more well known geoms that can be used for the geom ...
8 de may. de 2024 · Greetings, ggplot wizards 😉 After reading through chapter 14 Scales and guides from ggplot2: Elegant Graphics for Data Analysis, I would like to create two separate guides (legends), one for color and fill, one for linetype and alpha. While a variable is mapped to color and fill, linetype and alpha are set manually (i.e. as constants) depending on the layer and later mapped with manual ...
21 de may. de 2024 · geom, stat: Use to override the default connection between geom_quantile() and stat_quantile(). For more information about overriding these connections, see how the stat and geom arguments work. quantiles: conditional quantiles of y to calculate and display. formula: formula relating y variables to x variables. method: Quantile regression ...
21 de may. de 2024 · Rectangles Description. geom_rect() and geom_tile() do the same thing, but are parameterised differently: geom_rect() uses the locations of the four corners (xmin, xmax, ymin and ymax), while geom_tile() uses the center of the tile and its size (x, y, width, height).geom_raster() is a high performance special case for when all the tiles are the same size, and no pattern fills are applied.
Hace 2 días · Additionally geom_central_region uses the same aesthetics as geom_ribbon if filled==TRUE and geom_line otherwise. For multiple coverage values additional aesthetics are not currently supported. Computed variables. stat_central_region computes after_stat(ymax) and after_stat(ymin) for the high and low value of the central region.
21 de may. de 2024 · The geom's documentation has an Aesthetics section that lists the available options. The 'required' aesthetics cannot be passed on to the params . Please note that while passing unmapped aesthetics as vectors is technically possible, the order and required length is not guaranteed to be parallel to the input data.
