The Rmarkdown cookbook states that the working directory for r chunks in an

This may not be the right place to ask about ggplot which is part of
packages but are you aware how ggplot works additively?
You can say something like:
P <- ggplot(...) ... + ...
Then later say:
P <- p + geom_...()
And so on.
So if you set al the layers you want first into a variable like
How can I write an R function that contains a call to ggplot within it,
with one of the ggplot geom statements being conditional? In my reprex,
I want the plot to contain a horizontal zero line if the y values are
both positive and negative, and to exclude the horizontal line if all of
the y

I would like a real-life example of a data set which one might think to
model by a binomial distribution, but which is substantially
underdispersed. I.e. a sample X = {X_1, X_2, ..., X_N} where each X_i
is an integer between 0 and n (n known a priori) such that var(X) <<
mean(X)*(1 - mean(X)/n).
Please don't reply to a thread to start a new question... create a new email to
avoid linking your question with the one you replied to.

I ended up taking a different approach
miDat <- miDat %>%
mutate(new_cases = cases - lag(cases, default = 0))
- or -
df <- df %>%
mutate(diff = Score - lag(Score, default = 0))

I need help with my R programming code.
I just have a problem storing the matrix calculate Gsigma[m] in sigma.
Seeing what I have coded I find NA value which doesn't generate me errors.

Hello,
R is case sensitive, the column name is YEAR_END_Date, neither of
Year_END_Date
YEAR_END_DATE
matches that name. Try
select(PLC, format(YEAR_END_Date,format = "%B %d, %Y"), EPS)
Hope this helps,

Rather than diff-ing a linear vector you're trying to diff values from
two different rows. Also you indicate that you want to place the
diff-ed value in the 'lower' row of a new column. Try this (note
insertion of an initial "zero" row):

Indeed there was no scoping issue here. I was sloppy.

Dear Jeff,
read diff's help page, and you'll find out
what is wrong with your expectation.
What do think diff(df$Score) should give for
the first element in df$Score??
