If I had this problem, in the old days I'd've whipped up a tiny AWK script. These days I might use xsv or qsv. BUT first I would want to know why these extra fields are present and what they signify. Are they good data that happen not to be described in the documentation? Do they represent a def

Re: [R] Reading very large text files into R

To me this file looks like a CSV with 15 fields (on each line) not 16, the last field being empty with the exception of the one which has the 'B'. The 14th is always empty. I also note that it does not seem to have a new line at the end. I can strongly recommend QSV to manipulate CSV files and

Hello Ivan's suggestion of fill=T seems to do the trick. Thanks to everyone who piled in - I'm rather touched by the support seeing as this was causing me a big headache with furthering my project. I also feel humbled by realising how little I know about the R-universe... Nick On Thu, 29 Sept 20

"Confusion" is the size of the file. Try specifying the colClasses argument to nail down the number and type of the columns. On September 29, 2022 8:16:34 AM PDT, Bert Gunter wrote: >I had no trouble reading your text snippet with >read.csv(text = >"... your text... ") > >There were 15 columns.

Re: [R] Reading very large text files into R

I had no trouble reading your text snippet with read.csv(text = "... your text... ") There were 15 columns. The last column was all empty except for the row containing the "B". So there seems to be some confusion here. -- Bert On Thu, Sep 29, 2022 at 6:54 AM Nick Wray wrote: > Hello I

Re: [R] Reading very large text files into R

You're sure the extra column is indeed an extra column? According to the documentation (https://artefacts.ceda.ac.uk/badc_datadocs/ukmo-midas/RH_Table.html) there should be 15 columns. Could it, for example, be that one of the columns contains records with commas? Jan On 29-09-2022 15:54

Hi Nick, It's hard to know without seeing at least a snippet of the data. Could you do the following and paste the result into a plain text email? If you don't set your email client to plain text (from rich text or html) then we are apt to see a jumble of output on our email clients. ## start x
