Some introductory questions
Dear Mike, I remember so very well the time when I struggled with exactly the same things, reading a file seeming like an almost insurmountable task. However, given this actually is very simple I can also understand the reactions you got. Imagine every newbie asking these questions over and over again, in a time where there is so much information out there to figure it out quite easy. The documentation might be a little cryptic, I give you that. But there are so many other resources, most of them free, that you can read to understand how this works. I would warmly recommend some of the contributed introductory materials from: https://cran.r-project.org/other-docs.html There are also plenty of websites to teach R interactively, and all of them offer this kind of information, without exception, since this really is part of the very basics in R. What I learned over the years is that help on this list is invaluable. But all of the contributors share their own time, and help must be required in such a way that it (at least) makes it obvious you did first try to do your homework. Most of the time, asking the right question(s) reveals the answer and at some point you will only need to browse past similar questions to find the answer you want. Linked to that, one other thing I learned is my question is almost never unique and most likely somebody else asked something at least similar in the past. Doing your homework also means trying to dig in the archives, which is pretty easy these days using Google. Should you make this effort and make it evident in your question that you did try to read on your own, I'm sure it would be easy for other people to point you in the right direction. Because this is almost always what I need: a pointer, and then I can figure it out on my own. Rest assured this is a very friendly email list, and I consider myself lucky to be part of this community. Despite knowing this for so many years, I still make mistakes and consume too much of others' time. But at least I am aware of that, and extremely grateful for the help I get. I hope this helps, Adrian

Hi Peter,
Here is a snippet of the code I was trying to start with:
filepath1 <- file("/Users/michaelfeher/Documents/R
Documents/COVID19/20200906-1822-total-cases-jones.data")
filepath1
TotalCasesJones <- read.table(filepath1)
This definitely did not work for me.
Mike

4. I tried to read in a set of dummy space-delimited data saved in an absolute path on my computer, but it would not work. I tried something
in
another path that did not have a subfolder with a space in it (I.e. I
plan
on storing my data in a folder called ?R Documents? or something
similar)
and that didn?t work either, so I?m still wondering whether or not (a) things have to be in the library location (it seems like you could customize that) and (b) whether R recognizes spaces in file paths.
Try using file.choose() to locate files using a dialog and it will return
the full name. Spaces shouldn?t matter provided that everything is enclosed
in quotes. Most people don?t use absolute references. They set the working
directory and then just use the name of the file. See under the Misc menu.
Also, how do you "read in" the data? Usually, read.table() or somesuch
would be involved, although RStudio has an "Import data" functionality.
