Hi Bernardo,
I don't think that your function is doing anything like you expect it to do:
test <- data.frame(var1=c("a","b","c"),var2=c("d","e","f"))
test
var1 var2
1ad
2be

You have a data frame with two columns, the first thing you do is
extract the first value in th
In addition to Petr's remarks:
- why are you doing sum(mtcars)[1]? Do you want the sum of first column of
mtcars? In that case you should do sum(mtcars[,1]).
- similar remarks apply to your use of mean and sd.
Have you read an introduction to R?

Hi
Your HTML formatted message is scrambled so it is hard to understand what is
your problem. The probable cause is the fact that sum, mean and sd behave
differently when applied to different objects (vector, data.frame, ...)
Post in plain text together with at least result of
str(mtcars)

Hi Jim,
Nice to see you again! First of all, apologies to all for bending the rules a
bit with respect to the mailing list. I know this is a list for R programming
specifically, and I have received some great advice in this regard in the past.
I just thought this was an interesting applied prob
Hello list,
my first post but I've been using this list as a help source for a while.
Couldn't live without it.
I am writing a function that takes a dataframe as an argument and in the
end I intend to assign the result of some computation back to the
dataframe. This is what I have so far:
myFunc
I find your response here inconsistent... either including `return` causes a
"wasted" function call to occur (same result achieved slower) or the parser has
an optimization in it to prevent the wasted function call (only behaviorally
the same).
I carefully avoid using the return function in R.
Salvatore,
I won't comment on whether to use log weight "to increase the
correlation" -- that depends on whether that makes sense, and whether
the relationships with other variables is more nearly linear.
Try this with your pca of the correlation matrix:
biplot(pca_morpho)
You'll see that
Hi Salvatore,
Depending upon your concept of "size" the use of the weighted sum may
well suit your purpose. The first principal component, being three
lengths and a mass, is likely to be strongly related to any sensible
concept of "size". My comment was meant to ensure that the local
definition of
past versions of ggplot2 used to accept family as an argument directly, but
the latest ggplot2 (perhaps starting with v2?) requires method.args=list().
So the online sources you found using family directly were for an older
version of ggplot.

Hi,
It's hard to know for sure, but perhaps the spelling of 'binomial' is not
correct?

Hi. I’m a student from South Korea, and I’m studying R by myself.
While I am studying, I have a trouble dealing with ggplot(especially, about
parameter ‘family’)

hello all r users,
somebody has a example how to use fontchooser widget?
I haven't success in my try :-(
Thanks

Hi Salvatore,
If by "size" you mean volume, why not directly measure the volume of
your animals? They appear to be fairly small. Sometimes working out
what the critical value actually means can inform the way to measure
it.

Hi
Can you supply some example code?
You might get some joy from grid.ls() to identify the box followed by
grid.remove() to get rid of it; some example code would allow me to
provide more detailed advice.

While you may get a reply here, this list is about R programming, not
about statistics. So
1. Do your homework and read a tutorial on PCA on the web or
elsewhere. Isn't this what a PhD student is supposed to do?
2. Post on a statistics list like stats.stackexchange.com.
3. Consult your professor

Let's say I perform 4 measurements on an animal: three are linear measurements
in millimeters and the fourth is its weight in milligrams. So, we have a data
set with mixed units.
Based on these four correlated measurements, I would like to obtain one "score"
