Error in file(file, "rt")

[liu666]

I run the FluteRRA using testdata:rra.gene_summary.txt

file1 = file.path(system.file("extdata", package = "MAGeCKFlute"),"testdata/rra.gene_summary.txt")
gdata = read.delim(file1, check.names = FALSE)

FluteRRA(gdata, proj="Test", organism="hsa", outdir = "./")

‌

but get the error:

Error in file(file, "rt") : 无法打开链结
此外: Warning message:
In file(file, "rt") : InternetOpenUrl失败:’?E?'

how can i solve the problem？

thank you
