Hi!
If you have a Spatial Points Data Frame, you can use the following function
to create a grid:
create1 <- function(obj) {
# Function that creates a new_data object if one is missing
convex_hull = chull(coordinates(obj)[,1],coordinates(obj)[,2])
convex_hull = c(convex_hull, c
Don't start putting in extra commas and then reading this as csv. That approach
is broken. The correct approach is what Bill outlined: read everything with
readLines(), and then use a proper regular expression with strcapture().
You need to pre-process the object that readLines() gives you: rep
Very interesting. I'm sure I'll be trying to get rid of the byte order
mark eventually. But right now, I'm more worried about getting the
character vector into either a csv file or data.frame; that way, I can
be able to work with the data neatly tabulated into four columns:
date, time, person, comm
If byte order mark is the issue then you can specify the file encoding as
"UTF-8-BOM" and it won't show up in your data any more.

The pattern I gave worked for the lines that you originally showed from the
data file ('a'), before you put commas into them. If the name is either of
the form "" or "***" then the "(<[^>]*>)" needs to be changed so
something like "(<[^>]*>|[*]{3})".
The " " at the start of the imported data m
This seemed to work:

And the first 85 lines looks like this:
[83] "2016-06-28 21:02:28 *** Jane Doe started a video chat"
[84] "2016-06-28 21:12:43 *** John Doe ended
I fixed it by removing previous versions as suggested.

Thank you Mark, I was unaware of the RC distinction and the multiple R version
issue.
Appreciate your help.

This is actually a question about RStudio, not R, so is technically off topic.
However, I think the answer to your question is in the Global Options (General)
configuration screen.

Hello.
I do not think I have had this problem (assuming it is a problem) in the past.
I downloaded and installed R3.6.0 which is indicted in the console when I open
R itself.

Consider using readLines() and strcapture() for reading such a file. E.g.,
suppose readLines(files) produced a character vector like
x <- c("2016-10-21 10:35:36 What's your login",
"2016-10-21 10:56:29 John_Doe",
"2016-10-21 10:56:37 Admit#8242",

Hi all,
I'm trying to learn how to use xgboost. I'm working with the 2016 GSS dataset
(attached) and trying to determine what variables influence number of children.
I've successfully used this to teach myself GLMs, decision trees, and random
forests.
My problem is, I can't get the xgboost progr
