从git读取rds压缩文件

Question

我能够从git下载rds文件，但出现错误：

readRDS（temp）错误：在字符串'name \ 0'中嵌入nul

url <- "https://github.com/filename.rds"
temp <- tempfile()
download.file(url,temp,method="libcurl",quiet=TRUE)
print(temp)
unzipped <- gzcon(con=gzfile(temp), level = 6, allowNonCompressed = TRUE, 
text = FALSE)
print(unzipped)
result <- readRDS(unzipped)
close(con)    
unlink(temp)
