The explanation is likely that class(x) returns a character vector of
length > 1.
If you go into the code you can achieve what is probably intended without
triggering this error by replacing that statement with the following:

I have never used Spack but I took a quick look at their website. They have
the option to install binaries. Perhaps this could work for you and avoid
the compilation error. Here is where they describe how to do it:

This is because options(digits=3) specifies the number of significant

Hi,
To rephrase what you are trying to do, you want a copy of all the cp
columns, in which all the NAs become 1s and any other value becomes a
zero. There is an exception for the first row, where the NAs should
become 0s.
a <- c10Dt
b <- matrix(as.numeric(is.na(a[,-1])), nrow=nrow(a))
b[1,] <- 0
as.POSIXct(as.character(now),tz="UTC")
or
as.POSIXct(as.character(Sys.time()),tz="UTC")

Posit (formerly RStudio) has moved from RMarkdown to Quarto. They

new users a better choice would be Quarto.

Another direction would be to replace your R script (.R file) with a
Quarto document (.qmd file).
VS-code has good support for Quarto and you could intersperse your

Another approach (still seems to require experimentation to get the value
'2') would be to replace the annotate() with
geom_text(data=above_92, aes(x=eruptions,y=waiting, label=waiting),
nudge_y=2)
At least this makes clear the reason for the magic number '2' in the code.

You might want to consider exponential smoothing models such as Holt's

This method continually updates the trend parameter, and you can
monitor the most recent value (for sign, or magnitude, or both).

As Duncan points out, ifelse() provides a more general approach than
the specific pmax().
Even more generally, you might want to consider the apply() function
(and its relatives sapply(), lapply(), ...)
For example
apply(cbind(x1,x2), MAR=1, max)
In the above statement, x1 and x2 are combined i

Stacking columns of a matrix is a standard operation in multilinear

I checked to see if there is an R package that deals with multilinear
algebra. I found rTensor, which has a function vec().

Your problem is that the color "#4DAF4A8" is not a valid color. It should
have only 6 hex digits.
e.g. "#4DAF4A" will work.
Also you seem to be confused about ggplot. You are not using ggplot in your

You are using base graphics. You can remove the 3 library calls.

Hi Tiffany,
Here is some code that might help with your problem. I solve a "toy"
problem that is conceptually the same.
Part 1 sets up my toy problem. You would have to replace Part 1 with
your real case. The main point is to define
a function f(i, j, data) which returns 0 or 1 depending on whether
You can see all the installed vignettes on your system with

Alternatively `browseVignettes("pkgname")` for those related to a single
package.

Also, since your examples were dplyr and dbplyr which are associated
with RStudio.com (aka Posit) you might also try

Bert provided an excellent answer to your question.
FYI here is a different approach to do the calculation.
It uses data.frame rather than matrix. A data frame is a list of its columns.
Here the function supplied to sapply operates on each column of the data.frame.

?ga states that ga() searches for the maximum of the fitness function.
The maximum of your fitness function is at x=0.

In R 4.2.0 there is a significant change. When you use an if() statement
with a condition of length > 1 this now reports an error.

Hi Andrew,
If you look at ?source you see its default value for encoding is

You are misinterpreting what is going on.
The rbind command includes c(char, char, int) which produces a
character vector of length 3.
This is what you are rbind-ing which changes the type of the RT column.
If you do rbind(df, data.frame(P="in", ANSWER="V>N",
RT=round(runif(1,7000,16000),0)))

Hi Nick,
Here's one way to do it. It is based on the heuristic that you keep
each line with the correct number of fields. The correct number of
fields is automatically determined by the number of fields in the last
line of the file.

The model that you are fitting to the data is an AR(2) model, which means
y(t) = a0 + a1 * y(t-1) + a2 * y(t-2) + eps(t) (1)
The fitting procedure estimates the coefficients a0, a1, a2 (and the
variance of eps).
After the coefficients have been estimated, the fitted values can be

However, M[,!!x] is the same as M[,x==1] and saves one character!
The point of this is "I can name that tune in ... " (as if that was not
obvious)
