rcurl

I'm trying to fetch a JSON array from my server using the HTTP POST method in R. I've tried using both the POST function from httr and the getURL function from RCurl but both return errors. cafile <- system.file("CurlSSL", "cacert.pem", package = "RCurl") url <- "https://example.com/query/getData.php" POST(url,body=NULL) POST(url,body=NULL,config(cainfo=cafile)) getURL(url) getURL(url,cainfo=cafile) The error given by the POST function is (for both calls): Error in curl::curl_fetch_memory(url, handle = handle) : SSL peer certificate or SSH remote key was not OK The error given by the getURL

Is it possible to create a directory on an SFTP site using the RCurl package? I found the sftp_create_dirs function, but I could not find an example how to use it. I tried to set the ftp.create.missing.dirs option to TRUE , as in library(RCurl) opts <- list(ftp.create.missing.dirs=TRUE, ssh.public.keyfile = mypubkey, ssh.private.keyfile = myprivatekey) ftpUpload("myfile.txt", "sftp://me@www.host.org/newdir/myfile.txt", .opts=opts) This works if newdir exists, but fails if it does not exists. Any hint appreciated! 来源： https://stackoverflow.com/questions/20181690/create-an-remote-directory-using

My goal now is

I am trying to access data using httr library from server which expects certificate based authentication. I have certificate (cert.pem), key file (key.pem) and root certificate (caroot.pem) Following curl works. curl -H "userName:sriharsha@rpc.com" --cert cert.pem --key certkey.key --cacert caroot.pem https://api.somedomain.com/api/v1/timeseries/klog?limit=1 How can specify certkey.key and caroot.pem to httr GET request.

I am working with thousands of meteorological time series data (Sample data can be downloaded from here) https://dl.dropboxusercontent.com/s/bxioonfzqa4np6y/timeSeries.txt Plotting these data using ggplot2 on my Linux Mint PC (64bit, 8GB RAM, Dual-core 2.6 GHz) took a lot of time. I'm wondering if there is a way to speed it up or a better way to plot these data? Thank you very much in advance for any suggestion!

I'm using the ftpUpload function in the RCurl package to upload files to an sftp file server. I'm having difficulty working out the authentication call.
