ggplot2 density



ggplot2.density is an easy to use function for plotting density curve using ggplot2 package and R statistical software. The aim of this ggplot2 tutorial is to show you step by step, how to make and customize a density plot using ggplot2.density function. This function can also be used to personalize the different graphical parameters ...

A density plot is a useful way to visualize the distribution of values in a dataset. Often you may want to visualize the density plots of several variables at once. Fortunately, this is easy to do using the ggplot2 data visualization package in R with the following syntax:

幸い、ggplot2はy = ..density.. と指定するだけで、自動的に HDI_2018 のある時点における密度を計算してくれます。 したがって、マッピングは aes(x = HDI_2018, y = ..density..)

knitr::opts_chunk$set(message = FALSE) set.seed(71) library(ggplot2) x <- data.frame(price = rnorm(10000, mean = 6000, sd = 1000)) p <- ggplot(x, aes(x=price,y= ..density..)) p + geom_histogram(alpha = 0.3, binwidth=500, fill="red")+ geom_density(aes(colour="red",fill="red"), alpha=0.1, size=1.5) + ggthemes::theme_solarized()

 · library(reshape2) library(ggplot2) library(ggsci) data <- data.frame(CDS = rnorm(1000, 20, 5), exons = rnorm(1000, 25, 6), introns = rnorm(1000, 45, 6)) df <- melt(data) g <- ggplot(df, aes(x = value, y = ..density.., fill = variable)) g <- g + geom_histogram(position = "identity", alpha = 0.8) g <- g + geom_density(aes(color = variable, alpha = 0.2), show.legend = F) g <- g + scale_fill_npg() + …

ggplot2とは. ggplot2は、データをグラフ化するためのRのパッケージです。 R界の巨匠Hadley Wickham氏によって2005年にパッケージ名「ggplot2」としてリリースされました。 「The Grammar of Graphics」という本に記載されている体系を土台として設計されています。

ヒストグラムを描く場合、密度関数も同時に描きたい場合があります。密度関数はggplot2::geom_density関数で描けます。 # Usage geom_density(mapping = NULL, data = NULL, stat = "density", position = "identity", ..., na.rm = FALSE, show.legend = NA, inherit.aes = TRUE)

ggplot2で使用できる色のリストはこちら. data_2005 %>% ggplot(aes(x = exppv)) + geom_density(fill = "orange", # 曲線の中の色を変える color = "black") + # 線の色を変える labs(x = "有権者1人あたりに使う選挙費用", y = "密度", title = "選挙費用の密度曲線")

library (ggplot2) library (ggmap) nc <-get_map ("Persian Gulf", zoom = 6, maptype = 'terrain', language = "English") ncmap <-ggmap (nc, extent = "device") 他の層. ncmap + stat_density2d (data = sample.data3, aes (x = long, y = lat, fill =..level.., alpha =..level..

ggplot2ではmapping要素として「colorの違いはSpeciesで」と指定することで実現できます。なお、今回は離散変量でしたが、連続変量でも可能です: # aes内を変更 p_3_2 <- ggplot(iris, aes(x = Sepal.Length, y = Petal.Length, color = Petal.Width)) + geom_point() p_3_2
