我有一个类似以下的数据框:
mapDF <- structure(list(var = c(11L, 3L, 4L, 15L, 19L, 17L, 1L), approvals = c(10.5233545765422,
67.9809421770218, 9.66394835013545, 2.93736399165075, 3.36787205222721,
4.0168261757783, 1.50969267664431)), .Names = c("var", "approvals"
), row.names = c(NA, -7L), class = "data.frame")
当我尝试使用上述数据框创建条形图时,可以使用以下方法:
gplot <- ggplot(mapDF, aes(x= mapDF[1], y= mapDF[2])) + geom_bar()
我在 RStudio 中的“Plots”部分没有看到任何东西,同时收到以下信息:
Don't know how to automatically pick scale for object of type data.frame. Defaulting to continuous
Don't know how to automatically pick scale for object of type data.frame. Defaulting to continuous
Error: stat_bin requires the following missing aesthetics: x
请问有人能指出我的错误吗?
aes
内映射美学元素...? :) - jorangeom_bar
中使用stat = "identity"
