So this is a bug in openxlsx. It's also a well-known limitation of the
S3 object system: you can easily create things t

console), and parse only if it syntactically correct.
I was merely curious if this could be done, likely using regular
expressions (surely strsplit doesn't solve it).

See the section on "partial parsing" in the ?parse help page.
alculate log likelihoods is that rounding
error gives you a negative likelihood, and then log(lik) comes out to NaN.
You just need to look really closely at each step of your calculations.
Avoid using log(); use the functions that build it in (e.g. instead of
log(dnorm(x)), use dnorm(x, log =
data.frame, but when I reflect on the typical way a seasoned R programmer
approaches list and data.frames that is basically what they are
communicating.
I believe it is intended to be a requirement. You can construct things
with class "data.frame" that don't have that structure, but lots of
of them, things will slow
down noticeably.

Obviously wrong answer. So How can I have the right answer ?

The ls.str() function probably does what you want.
If you wanted to do it with sapply (e.g. because you want just typeof(),
not everything else), you need to take account of the fac
d the rgl.init problems by setting the environment variable
RGL_USE_NULL to TRUE before running anything. That should help on your
3.2.3 servers. It's possible that the segfault on the other system is
related, but I'd guess it's something else. Tracking down segfaults can
be hard: you'll nee

regular R, but I would prefer not to be constrained to that platform if
possible.
Since this is RStudio-specific, you'll need to ask on one of the RStudio
forums.

t's an example where the proposed behaviour makes sense. But
stopifnot(is.data.frame(df)); stopifnot(is.integer(df$ID))
isn't that much harder to type, and it already does what you want.

f(data.frame(ID=4:7))
# [1] 4 7
f(4:7)
# Error in df$ID : $ operator is invalid for ato
those
errors, so I don't think I'd change it.

t labels at some of those locations; R will leave some out, if
it looks as though the labels will overlap. Using las=2 will make them
perpendicular to the axis, and all should be drawn.

they do happen in plain R, try running with the --vanilla option. If
that is fine, the problem is probably something you have in your saved
workspace, or in one of the startup files.

ter(df$TSTMean), dec = ",", as.is = TRUE) instead
of as.numeric().
A simpler approach might be to avoid getting the factor in the first
place; if you read this data using read.table, there is the dec option
to recognize a comma as the decimal separator.

It is also possible to pass expressions that aren't in functions, but it
gets tricky, and you shouldn't do that in your first attempt.

Furthermore, I think I have to create a matrix using the formula above but I do
not know how to do that in this connection. Can any body help me with the code
for this purpose?
Thanks a lot in advance.

By far the easiest ways to enter Windows file paths are using the
file.choose() and choose.files() functions. Do something like
filename <- file.choose() # navigate to the file
mammals <- read.csv(filename)
and you should be fine. The file.choose() function works on all
platforms; choose.fil
.
"Avoided" may be too strong: speed isn't always a concern, sometimes
clarity is more important. Growing vectors is definitely expensive.

Thank you for your help!
