如何使用R中的数据帧列表绘制图表
我在一个列表中有几个数据帧(40),我需要一种方法来创建一个图表,可以使用如何使用R中的数据帧列表绘制图表,r,ggplot2,graphics,plotly,r-plotly,R,Ggplot2,Graphics,Plotly,R Plotly,我在一个列表中有几个数据帧(40),我需要一种方法来创建一个图表,可以使用plotly或ggplot2 我在下面放了一个示例模板,说明我目前如何创建图表 aa <- c("José", "Sue") ab <- c(10, 40) a <- data.frame(aa,ab) ba <- c("Marie", "Pablo") bb <- c(25, 20) b <- data.frame(ba,bb) ca <- c("Elizabeth", "M
plotly
或ggplot2
我在下面放了一个示例模板,说明我目前如何创建图表
aa <- c("José", "Sue")
ab <- c(10, 40)
a <- data.frame(aa,ab)
ba <- c("Marie", "Pablo")
bb <- c(25, 20)
b <- data.frame(ba,bb)
ca <- c("Elizabeth", "Mike")
cb <- c(50, 20)
c <- data.frame(ca,cb)
abc <- list(a,b,c)
names(abc) <- c("a","b","c")
p <- plot_ly() %>%
add_trace(type = 'bar', x = abc$a$aa,
y = abc$a$ab, visible=T, marker = list(color = 'blue')) %>%
add_trace(type = 'bar',x = abc$b$ba,
y = abc$b$bb, visible=F, marker = list(color = 'red')) %>%
add_trace(type = 'bar', x = abc$b$ba,
y = abc$c$cb, visible=F, marker = list(color = 'yellow')) %>%
layout(
updatemenus = list(
list(
yanchor = 'auto',
buttons = list(
list(method = "restyle",
args = list("visible", list(T, F,F)),
label = 'a'),
list(method = "restyle",
args = list("visible", list(F,T, F)),
label = 'b'),
list(method = "restyle",
args = list("visible", list(F, F,T)),
label = 'c')
))))
p
aa从数据列表中绘制所有数据。框架可以使用基本函数完成
par(mfrow = c(1, length(abc))) # optional, divides plotting area
lapply(abc, FUN = function(x) barplot(x[, 2], names.arg = x[, 1]))
但是,覆盖现有绘图需要针对所需data.frame执行选择步骤
i <- readline("Enter the name of the data: ")
我调整了您的代码,使其在循环中运行
library(plotly)
p使用lappy
和rect
不是更容易吗?@nya我在r:dthaaaanks中是n00b!很高兴这有帮助!
for(i in 1:length(abc)){
...
waiting <- readline("Press enter to view next plot")
}
# finds plotting area limits
lims <- max(unlist(lapply(abc, function(x) x[,2])))
# plots chosen data
barplot(abc[[i]][,2], names.arg = abc[[i]][,1], ylim = c(0, lims))
library(plotly)
p <- plot_ly()
layout_buttons <- list()
color_list <- palette() #color list - you may define your own list of colors here
visible_default_layout <- c(T, rep(F, length(abc)-1))
for (i in seq_along(abc)){
p <- p %>% add_trace(x = abc[[i]][[1]], y = abc[[i]][[2]],
