Error in ggplot(data = penguins) : object 'penguins' not found
trial:
ggplot(data=penguins) +
geom_point(mapping = aes(x=flipper_length_mm, y=body_mass_g, color=g))
to generate scatter plot. But I am facing following error everytime.
error:
Error in ggplot(data = penguins) : object 'penguins' not found
Help: Please rectify exactly what should I correct in the code.
thanks

你试图使用ggplot绘图，但没有提供数据（数据丢失）。你还没有创建颜色向量。
确保也加载了ggplot2包。
# 加载包
library(ggplot2)
library(palmerpenguins)
data(penguins) # 加载数据
ggplot(data=penguins) + geom_point(mapping = aes(x=flipper_length_mm, y=body_mass_g))
英文:
You tried to ggplot it, without data (The data is missing). The colors vector you did not create.
Be sure to load the ggplot2 package too
# Load the packages
library(ggplot2)
library(palmerpenguins)
data(penguins) # Load the data
ggplot(data=penguins) + geom_point(mapping = aes(x=flipper_length_mm, y=body_mass_g))
