生物学家应该这样学R绘图-视频,数据,代码全公开
作者是Maria Nattestad,生物信息学专业的博士,为冷泉港的OMGenomics实验室的创始人。
为什么推荐这个课程
作者虽然是生物信息学数据分析领域的实力战将,但是却仍能不忘初心,录制并且整理这样的初学者教程,而且把生物信息学领域的数据特性高度整合到了R绘图知识点里面。不再是大家看到的其它R教程那样可视化一些商业金融互联网数据,在学习的过程中能加上对生物信息学的理解,包括基因组,染色体,基因结构,GWAS。BED,CNV,GFF等等。
而且课程非常简洁,系统性很好,绝不拖拉,不会耗费大家的时间。
当然,你首先得自己安装好 R and RStudio
课程大纲
Lesson 1: A quick start guide — From data to plot with a few magic words

Lesson 5: Tweaking everything in your plots — Everything from color schemes to fonts to grid lines and tick marks, this lesson will show you how to change just about anything in a plot. Especially useful for creating plots for publication.
Lesson 6: Plot anything! — Quick guide to each plot type including which types of data fit into each one.
- Bar plots
- Scatter plots
- Box plots
- Violin plots
- Density plots
- Dot-plots
- Line-plots for time-course data
- Venn diagrams
Lesson 7: Multifaceted figures — Splitting up your data by some column into multiple plots arranged in rows, columns, or even tables.
