It was changed... in a new copy of the data frame that, because it was at the
top-level interactive prompt and not being saved, was printed and then
discarded.

Were you thinking of the %<>% operator? That's a magrittr thing, where
x %<>% y acts like x <- x %>% y .

False. Mutate is similar in structure to the base function `within`. Which is
why you have to assign the altered data frame back onto itself.

Jeff,
mutate(), which is I think part of dplyr, also violates this, for what it's
worth. I suspect the breaking point is that mutate() is intended to create
new columns in the dataframe, not alter existing ones.

R is largely a functional language. You do something to an input and end up
with an output that has no effect on the input. This is actually a highly
desirable feature.
If you want your df variable to reflect changes made then you need to assign
your result back into it.
df <- df %>% mutate(v
This seems needlessly complicated.
df$v1 <- as.double(df$v1)
Or as.numeric()

In a statement like:
df %>% mutate(v1 = as.double(v1))
I expect the variable v1 in dataframe df to have been converted into a double.
However, when I do:
str(df)
v1 still shows as int. Do I need to save the modified dataframe after mutating
a variable?

Hello,
I believe the error message comes from the last line, getQuote returns a
data.frame with a Date column and log(aaa) will try to log a date.
Error.
log(aaa[-1]) works, maybe the OP wants to revise the code and then come
back to this or other thread.
Hope this helps,

Hello,
OK, now it's reproducible, thanks.
align = "hv" works like I had suggested.
The full code is now
library(ggplot2)
library(cowplot)
s <- ggplot(data = subset(iris, Species == 'virginica'),
aes(Sepal.Length, Sepal.Width)) + geom_point()
v <- ggplot(data = subset(iris, Species == 'setosa'

What is the error message? Knowing this may help others diagnose the
problem.

Dear Spencer Graves (and Rasmus Liland),
I've had some luck just using gsub() to alter the offending ""
characters, appending a "___" tag at each instance of "" (first I
checked the text to make sure it didn't contain any pre-existing
instances of "___"). See the output snippet below:

Hi all,
I want to calculate interanual (not year to date) variation of a stock, I
am able to obtain year to date with annualReturn, but no way to obtain the
interanual increase. It says me no numerical output.
Can anyone guide me to obtain it.

Dear Chris
Just send it to the maintainer Achim Zeileis to whom I have cc'ed this
