这里的乳腺癌表达量矩阵数据集更多

前面我们分享了 你还缺乳腺癌表达量数据集吗,里面有34个数据集,然后热心的粉丝赶快留言了另外一个包:MetaGxBreast ,里面的数据集更多。同样的也值得介绍

安装和加载MetaGxBreast相信已经无需我多说了:

BiocManager::install('MetaGxBreast') 
library("MetaGxBreast")

这个包MetaGxBreast整理好的数据集超级多:

使用 loadBreastEsets 函数实时下载

可以一次性下载多个数据集,得到一个列表

 esets = MetaGxBreast::loadBreastEsets(loadString = c("CAL", "DFHCC", "DFHCC2", "DFHCC3", "DUKE", "DUKE2", "EMC2"))[[1]]

这个 esets列表的每个元素都是一个 独立的ExpressionSet对象,后面可以做个性化分析
