similar to: Can R load a saved workspace from the Internet?

Dear All, To load a previously saved workspace, one can do the following: load("/path/to/the/saved/workspace/file") However, if the path to the saved workspace file is a web address, one gets the following error: ?Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection In addition: Warning message: In readChar(con, 5L, useBytes = TRUE) : cannot open compressed file

Hi again, I hope this is the right place to post my question on running R within Ubuntu, however if not, any pointer on right distribution list will be helpful. I am currently using R in Ubuntu which is hosted in Amazon - AWS. I have a .Rdata file in AWS which I am trying to load in R. Used following code, however, fails to load showing some permission issue. However that same .Rdata file is

I've noticed that ff uses the unzip utility available on it's host OS to load datasets via ffload. It seems to work fine in linux, but when I try to use the package in Windows (hence dling Windows unzip utils) I get 2 errors, one telling me that the options aren't being passed to unzip correctly and another indicating that my filename is incorrect. First, does anyone know of an unzip

Hi Christofer, The directory /srv/shiny-server would normally be owned by the root user. Your options would seem to be to either (1) bring up the R session as root (dangerous) or (2) try copying the file to your local directory and read it from there (if allowed). e.g. from the Unix shell: > cd ~ (i.e. cd to your home directory) > cp /srv/shiny-server/Dat.Rdata . (Note the '.' at

Hi, I started playing around with a function for using StatTransfer (version 10) for importing data. This started as a simple task but it's not working and so now I'm very frustrated. I'm using R version 2.13 on Windows 7. The function, called fn.importData, is: function(file = NULL, type = NULL){ ## ## create statTransfer command file -

Thanks Eric for your pointer. However I just altered the argument of load() function a little bit to get that loaded. Below is the line what I tried. ubuntu at ip-172-31-23-148:~$ R R version 3.4.2 (2017-09-28) -- "Short Summer" Copyright (C) 2017 The R Foundation for Statistical Computing Platform: x86_64-pc-linux-gnu (64-bit) R is free software and comes with ABSOLUTELY NO

Dear All: I am trying to load an R data set, but I got the following message. Please see below. The file is there. setwd("F:/Fall_2017/5-STA574/2-Notes/1-R/1-R_new/chapter4-Entering_Data") datahs0csv <- read.table("hs0.csv", header=T, sep=",") attach(datahs0csv) detach(datahs0csv) rm(list=ls()) Then I tried to reload the data, but I got this error message. I

Hi Christofer, The shiny code you have written does not depend on loading the Dat.RData file. I commented out that line and ran your shiny app on my machine and it works fine. What happens if you comment out (or remove) the line load("/home/ubuntu/Dat.RData) Does your shiny app still fail? If so, then your problem is quite basic with your AWS setup. Try to work through a simple

Hi Eric, thanks for your further pointer. I have put a line with load() function just as an illustration of a bigger project of mine, which appears failing due to load() function issue. If I comment out that line my shiny app is working correctly locally and globally. otherwise, locally my shiny app is working but not with AWS.

Hi Abou, You haven't saved the datahs0csv. When you are done manipulating datahs0csv you can use save(datahs0csv, file = 'datahs0csv.rda'). Then you should be able to load the data.

Dear All: It was saved, but there was a space somewhere. So it works for me now. I do have another similar problem. I saved an R data file save(datahs0csv,file=" F:\Fall_2017\5-STA574\2-Notes\1-R\1-R_new\chapter4-Entering_Data/datahs0csv2 .rda") *The new R data file "*datahs0csv2.rda*" is in the directory.* I tried to load the file "" to R, but I got an error

The object you load has the same name as the object you saved. In this case datahs0csv and not the name of the file sans .rda On Di., 12.

Hi, I was trying to have R read files faster with readChar(). That was before I noticed that readChar() is not that bad! In any case, below I suggest a few simple changes that will make readChar slightly faster. I followed readChar(useBytes=T), and tried to identify all O(N) operations, where N is the size of the file. The assumption is that for LARGE files we want to avoid any O(N) operations,

I have inherited some S-Plus code and objects that I am trying to get to work in R. The object files (3 __i files and one ___nonfi file) are stored in a folder (named _Model), but when I try to use "attach("c:/_Model")" I get an error saying "Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection" Any help with this issue would be greatly

Hi, I am trying to read in records from an old main frame file. Each record is 640 bytes. I had some success using the following statement: iconv(readChar(con, nchars=640, useBytes = TRUE),from="IBM037",to="",sub="#") What I have found, however, is that ocassionally a record will contain a Null halfway through, which causes readChar() not to read the rest of the

Hi, I have a flat file that contains a bunch of strings that look like this. The file was originally in Unix and brought over into Windows: E123456E234567E345678E456789E567891E678910E. . . . Basically the string starts with E and is followed with 6 numbers. One string=E123456, length=7 characters. This file contains 10,000's of these strings. I want to separate them into one vector the

Hi, I am developing a tool for converting a large data frame stored in an uncompressed binary (XDR) RData file to a delimited text file. The data frame is too large to load() and extract rows from on a typical PC. I'm looking to parse through the file and extract individual entries without loading the whole thing into memory. In terms of some C source functions, instead of doing

Dear all, I am a new user of R, here I have a question about remove the previous restored workspace. I saved the workspace last time, but R always automatically load the workspace when I open it. I try to remove the object and then close R without saving. But next time when I open R, it always load the previous workspace. I want to delete the .RData in the directory, but I have no clue
