各位大神好！我最近在学习用R语言包RTCGAToobox下载TCGA数据，但是总是失败，报错：
Error in file.rename(from = fileList, to = destfile) :
expanded 'from' name too long
请问一下，这个是什么原因啊？谢谢！
R语言包下载TCGA数据
代码有问题，参数名有误，改成
library(RTCGAToolbox)
data=getFirehoseData(dataset = "BRCA",runDate = "20140115",Clinic = TRUE,
RNAseq_Gene =TRUE,mRNA_Array = TRUE,Mutation = TRUE ) 之后可以运行了，不过一看要下个276M的东西吓得立马关了= =
而且看样子还是下到个R进程里
这么大的数据还是建议直接到他们网站上下，然后读进R里处理：

谢谢你耐心的回答！代码应该没问题吧，我之前的代码能运行，它运行的结果如下
data=getFirehoseData(dataset = "BRCA",runDate = "20140115",clinical = TRUE,
+ RNASeqGene =TRUE,mRNAArray = TRUE,Mutation = TRUE )

Error in file.rename(from = fileList, to = destfile) :
expanded 'from' name too long我猜测是否是因为文件名太长了，然后我改了文件名之后再运行，结果如下

In addition: There were 50 or more warnings (use warnings() to see the first 50)不知道到底是哪里出问题了，谢谢！
