similar to: default destfile in download.file()

Hello, I run R 4.2.2 on CentOS-7.6. I install package through install.packages("sf").It threw the above error: > install.packages('sf') --- Please select a CRAN mirror for use in this session --- *** caught segfault *** address 0x60, cause 'memory not mapped' Traceback: 1: download.file(url, destfile = f, quiet = TRUE) 2: doTryCatch(return(expr), name, parentenv,

Dear Ruser, I am trying to use the map library. But I have been problem the follow message. Warning message: *In readGDAL(destfile, silent = TRUE) : GeoTransform values not available * library(rgdal) library(RgoogleMaps) > GetMap(markers = '40.702147,-74.015794,blues%7C40.711614,-74.012318,greeng%7C40.718217,-73.998284,redc', destfile = "MyTile1.png"); Read 1 item [1]

Dear all, I am looking for a way to work out if a file on the internet exists before attempting to download it using the function download.file(). 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

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" >

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"

I am planning to download a large number of files from some website. I am using the following script. files2down = c('aaa', 'bbb', ................) for (i in 1: len) { print(paste('downloading file', i, ' of total ', len)); url = paste(urlPrefix, files2down[i], sep='') destfile = paste (dest, 'inDir', files2down[i], sep='/' )

R-devel r69197 returns appropriate errors for the cases below; I know of a few rough edges - ftp error codes are not reported correctly - download.file creates destfile before discovering that http fails, leaving an empty file on disk and am happy to hear of more.
