[有偿专区]TCGA 预后作图
这是我们论坛开张以来第二次做有偿服务推广,上一次很成功,大家可以点击看看:
[有偿专区]随机抽样批量做差异分析 (1200成交,我们平台抽200)
本次要推广的同样是一个医生关于R语言可视化及统计方面的需求,原文如下:
在阅读文献的时候遇到了相关问题。如下图如何做?
上图所示为Development of a RNA-Seq Based Prognostic Signature in Lung Adenocarcinoma文章提到的,但是没有讲如何做出来的
请大神赐教。谢谢
有重谢。(报酬暂定为1000元,但是平台需要抽成200)
其实在其它文章我也看到了类似的图,比如下面这个:
发表在
An eight-miRNA signature as a potential biomarker for predicting survival in lung adenocarcinoma
请大神给出意见。
文章说了:
To evaluate the contribution of miRNAs as independent
prognostic factors of patient survival, we used a
multivariate analysis. All variables reaching a significant
level of 10% in univariate analyses were tested in a Cox
proportional hazards model. All reported P values were
two-sided. All analyses were performed using the R/Bio-
Conductor (version 3.0.2) [19] and survival curves and
ROCs were generated by ggplot2, survMisc and survivalROC
[20] packages.
可能用了以上者三个包 。
原文已经结束了,感兴趣的朋友在下面留言吧,或者在后台回复,表明你愿意并且有能力解决这个问题。
要求,附上代码,测试数据,成图,且给予不少于10分钟的语言讲解,讲清楚!
其实就是一个生存分析的函数用来做predict,然后加上表达数据的热图,上面两个图原理是一样的。
