For example, using a url that does not exist url <- "http://finance.yahoo.com/ftse.csv" destfile <- tempfile() download.file(url = url, destfile = destfile) # gives the following response ... trying URL

Hello, I see the following issue in R-devel since 'both' has become the default pkgType for binary platforms. update.packages() fails when you set options(repos). Looks like it is trying to download a tgz file from the src/contrib section of a repository (on a mac). To reproduce this you need to have an older version of AnnotationDbi installed, which I accomplished by faking it,

I am downloading say 100 files from ucsc website and storing it into dest folder. download.file function create a file in destination folder even if the file is not present which is something I dont want. So I wrote if condition to remove the file if the download function has non zero value. Now it exits when there is an error or file not present. How can I use "try" and "if"

Dear R-Help, >From reading the help file, it is my understanding the the download.file() function does not support HTTPS connections. So therefore, understandably, the follow produces an error: ### R Code > url <- "https://stat.ethz.ch/pipermail/r-help/2008-October/thread.html" > destfile <- "//PFO-SBS001/Redirected/tonyb/Desktop/R_web_test/tmp.txt" >

A nice default value for the `destfile` argument in download.file() would be `basename(url)` i.e. the name of the downloaded file. This would correspond to default behavior in many other web/ftp clients and makes code slightly more concise: download.file("https://svn.r-project.org/R/trunk/doc/CRAN_mirrors.csv") mirrors <- read.csv("CRAN_mirrors.csv") [[alternative
