情节中的文字出现错误|Jupyter-R [英] Error with text in plot | Jupyter - R

问题描述

我正在尝试通过Anaconda安装在Jupyter笔记本上的R中的ggplot2在ggplot2上绘制一些数据的简单散点图.以下是我使用的代码:

I am trying to plot a simple scatterplot with some data using ggplot2 in R on Jupyter notebook installed through Anaconda. Following is the code I used:

ggplot(data = df1 [1:1000，])+ geom_point(mapping = aes(x = val1，y = val2))

结果如下:

我在使用正常绘图功能时遇到了同样的问题.对于命令-

I am experiencing the same issue with normal plot function. For the command -

df <- data.frame(x=rnorm(10000),y=rnorm(10000))
plot(df[1:1000,1],df[1:1000,])

我得到以下结果:

这是sessionInfo()

I've tried reinstalling the packages but the problem still persists. Kindly tell if anyone knows what's the problem here and how to fix it.

感谢所有人.

推荐答案

这是Anaconda默认不安装字体的问题.解决方案是安装一些字体:

This is an issue with Anaconda not installing fonts by default. The solution is to install some fonts:

conda install -c anaconda fonts-anaconda
