im using R package httr to get a HTTP-Response for a specific link.
When trying to parse the content of the response im getting the Error:
Fehler in parse(text = script_content) : <text>:1:10: Unerwartete(s) '['
1: {"lines":[
Translated to enlgish it says something like this (sorry for my error messages being in German):
Error in parsing(text = script_content) : <text>1:10: Unexpected '['
1: {"lines":[
It seems as there is a problem with the format/encoding of the text. Here is my code:
script <-
GET(
url = "https://my_url.which_origin_is_not_important/my_script.R",
authenticate(username, pass)
)
script_content <- content(script, as = "text", encoding = "ISO-8859-1")
parsed_condent <- parse(text = script_content )
The value of script_content looks like this:
"{\"lines\":[{\"text\":\"################## FUNCTION ##################\"},{\"text\":\"\"},{\"text\":\"library(log4r)\"}],\"start\":0,\"size\":32,\"isLastPage\":true,\"limit\":500,\"nextPageStart\":null}"
Some more background to this operation: Im trying to source a code, which is currently inside of a private repository. I wrote the code myself i'm trying to source. I made sure, that the issue is not coming from within th code.
I got the solution from: Sourcing R files in a private github folder
Thanks for any advice!!

I'm using dada 2 version ‘1.22.0’ on windows 10, i have list of compressed (.gz ) fastq files, when i use the function filterAndTrim i get this error message :
Error in add(bin) : record does not start with '#'
But when i want to see if i can read th .gz file with library(ShortRead) :
library(ShortRead)
fn <- "path/to/example.fastq.gz"
reads <- readFastq(fn)
it doesn't give any error message message
I don't understand why the function filterAndTrim give the error message
Error in add(bin) : record does not start with '#'
Do you have any solution?
I am trying to use pdf2image, but I am getting this error:
PDFPageCountError: Unable to get page count.
I/O Error: Couldn't open file 'C:\Users\user_name\Desktop\folder_name\folder2_name\folder3_name\007-084841-1 to 31 Dec'22': No error.
It is confusing as it doesn't give any error, it just says 'No error'
My code is:
doc = convert_from_path("C:\\Users\\user_name\\Desktop\\folder_name\\folder2_name\\folder3_name\\007-084841-1 to 31 Dec'22")
path, fileName = os.path.split("C:\\Users\\user_name\\Desktop\\folder_name\\folder2_name\\folder3_name\\007-084841-1 to 31 Dec'22")
fileBaseName, fileExtension = os.path.splitext(fileName)
for page_number, page_data in enumerate(doc):
txt = pytesseract.image_to_string(Image.fromarray(page_data)).encode("utf-8")
print("Page # {} - {}".format(str(page_number),txt))
Can anyone help me please?
I don't know what to try as the error message just says Unable to open...: No error
I am attempting to use a targets workflow in my R project. I am attempting to download water quality data using the dataRetrieval package. In a fresh R session this works:
dataRetrieval::readWQPdata(siteid="USGS-04024315",characteristicName="pH")
To use this in targets, I have the following _targets.R file:
library(targets)
tar_option_set(packages = c("dataRetrieval"))
list(
tar_target(
name = wqp_data,
command = readWQPdata(siteid="USGS-04024315",characteristicName="pH"),
format = "feather",
cue = tar_cue(mode = "never")
)
)
when I run tar_make() the following is returned:
* start target wqp_data
No internet connection.
The following url returned no data:
https://www.waterqualitydata.us/data/Result/search?siteid=USGS-04024315&characteristicName=pH&zip=yes&mimeType=tsv
x error target wqp_data
* end pipeline
Error : attempt to set an attribute on NULL
Error: callr subprocess failed: attempt to set an attribute on NULL
Visit https://books.ropensci.org/targets/debugging.html for debugging advice.
Run `rlang::last_error()` to see where the error occurred.
I have attempted debugging using tar_option_set(debug = "wqp_data") or tar_option_set(workspace_on_error = TRUE) but outside of isolating the error to readWQPdata() didn't get anywhere.
I also had success using curl directly in targets so I do not think it is my actual internet connection:
list(
tar_target(
name = wqp_data,
command = {con <- curl::curl("https://httpbin.org/get")
readLines(con)
close(con)}
)
)
tar_make()
* start target wqp_data
* built target wqp_data
* end pipeline
Any advice on how to diagnose the connection issue when using these two packages?
I have been trying to connect to Adwords Account using RAdwords, but I get the following error on doAuth():
Error in
rjson::fromJSON(RCurl::postForm("https://accounts.google.com/o/oauth2/token",
: STRING_ELT() can only be applied to a 'character vector', not a
'raw'
I have the correct credentials and Developer's token, but I am still unable to resolve the problem. I am using windows 7. The traceback is as follows:
> traceback()
4: .Call("fromJSON", json_str, unexpected.escape, simplify, PACKAGE = "rjson")
3: rjson::fromJSON(RCurl::postForm("https://accounts.google.com/o/oauth2/token",

Looked and tried all options from other similar questions, e.g.: using suggestions), I have also installed this version of RAdwords.
install_github('jburkhardt/RAdwords', ref = "refresh_token_raw_data")
Install the RAdwords package from the following GitHub branch containing a bug fix for your issue:
require(devtools)
install_github('jburkhardt/RAdwords', ref = "bugfix_char_to_raw")
I recently rewrote a package to use the new(er) R reference class objects. I've exported the three classes using export() in the NAMESPACE file so as far as I'm aware that should work. However when I test build the package I get an error at lazy loading stage:
** preparing package for lazy loading
Error in file(con, "rb") : invalid 'description' argument
ERROR: lazy loading failed for package ‘PACKAGE_NAME_HERE’
* removing ‘/Library/Frameworks/R.framework/Versions/3.0/Resources/library/PACKAGE_NAME_HERE’
I'm not sure what the problem is here. I don't know if it's relevant but the reference classes do store data on files in the tmp directory by having some fields set as accessor functions - I don't know if that's what s being complained about here when it says (con, "rb") which I guess is some connection thing. Does anybody have any ideas or advice for making sure reference classes get exported properly? My namespace is currently simple -
export(Main)
export(Mainseq)
export(Maintriplet)
Which are the three reference classes I exported by using #export tags in roxygen2.
What is it I'm doing (or not doing) that is throwing the lazy load error?
(ASIDE - I have no compiled code - all R, although the reference class methods do call some internal functions that are not exported, but these are supposed to be internal so I don't think I need to export them.
Thanks,
Ben.
EDIT:
My description file is as follows:
Package: HybRIDS
Type: Package
Title: Quick detection and dating of Recombinant Regions in DNA sequence data.
Version: 1.0
Date: 2013-03-13
Author: Ben J. Ward
Maintainer: Ben J. Ward <b.ward#uea.ac.uk>
Description: A simple R package for the quick detection and dating of Recombinant Regions in DNA sequence data.
License: GPL-2
Depends: ggplot2,grid,gridExtra,png,ape
I can't see what is wrong with this - the Depends are correct.
EDIT:
I've eliminated the first error with the description but I'm still getting the con error.
I think it's because the Mainseq class (which is nested in class Main) has some fields:
FullSequenceFile = "character",
FullSequence = function( value ) {
if( missing( value ) ){
as.character( read.dna( file = FullSequenceFile, format = "fasta", as.matrix = TRUE ) )
} else {
write.dna( value, file = FullSequenceFile, format = "fasta" )
}
},
InformativeSequenceFile = "character",
InformativeSequence = function( value ) {
if( missing( value ) ){
as.character( read.dna( file = InformativeSequenceFile, format = "fasta", as.matrix = TRUE ) )
} else {
write.dna( value, file = InformativeSequenceFile, format = "fasta" )
}
}
The idea being upon initialisation, the two character fields are filled with a path to a temp file in tmpdir, and when the variables are called or edited the files containing the variable data are read or written to. However it seems the variables are being accessed before this path is available because up package build the following happens:
** preparing package for lazy loading
Warning in file(con, "rb") :
