Re: [R] Help with first S3-class

Function arguments are not pass-by-reference... they are pass-by-value. You need to return the altered object to the caller when you are done messing with it. Note that R is a data processing language... your example will not scale to real world use cases because you make no use of vectorizatio

Re: [R] httr::content without message

That's good to know about when to auto-parse and when not to. There is quite a big stable of tools to check the response before you try to read... > httr::http_error(r1) [1] FALSE > httr::http_status(r1) $category [1] "Success" $reason [1] "OK" $message [1] "Success: (200) OK" and > httr::h

Re: [R] httr::content without message

Thanks to all that replied. I had just looked through the httr code and sure enough for a .csv mime time it calls readr::read_csv(). The httr::content docs suggest not using automatic parsing in a package, rather to determine mime type and parse yourself and Ben's suggestion also works if I d

Re: [R] httr::content without message

You can suppress all messages from that command with junk <- suppressMessages(httr::content(r1)) If you only want to suppress that specific message you can use withCallingHandlers: junk <- withCallingHandlers( httr::content(r1), message=function(e){ if (grepl("P

Re: [R] httr::content without message

Ahoy! That's a message generated by the readr::read_table() function (or it's friends). You can suppress it a number of ways, but this should work as httr::content() will pass through arguments, like col_types = cols(), to the file reader. junk <- httr::content(r1, col_types = cols()) See mo

[R] httr::content without message

Hi All: I am using httr to download files form a service, in this case a .csv file. When I use httr::content on the result, I get a message. Since this will be in a package. I want to suppress the message, but haven't figured out how to do so. The following should reproduce the result: m

Hi Rolf, I looked at https://docs.microsoft.com/en-us/azure/sql-database/sql-database-public-data-sets One of the first sets in the list is the airline time series (I think it is also used in dplyr examples). https://www.transtats.bts.gov/OT_Delay/OT_DelayCause1.asp You might find other possibil
