Dear Users of R,
I have this following confusion.
I want to download 3 hourly TRMM data from NASA website by using R, from the
following website

Hello, I am trying to use a code which requires quotes around each of about
1000 entries. When I did this in Microsoft programs, R rejected every quote. I
converted the font to courier new size 10 true type (the R default). No luck. I
had to find a sample code and copy the quotes from that 2000
I'm trying to create a
series of demos for students.
It would be helpful
if plotted data points
could appear one by one
with, say, half-second delays
between points.
For instance,
code like this
v<-0:60
z<-3/5+4i/5
t<-z^(v/9)
plot(Re(t),Im(t))
would be better if I
could invoke some

I was trying to do the same job in different way because it is easier to

missing here?

Thank you, Jim.
Just to understand it:
You replicated 10 times: "1970-01-01". Why this specific date?

Hi Sarah,
I used the following to clean my data, the program crushed several times.
*test <- dat[dat$Var1 == "YYZ" | dat$Var1 =="MSN" ,]*

Hi Omar,
There is some sort of error in your structure definition, but the following
works for me:
session.duration.fuente <-
data.frame(mes=c(rep("oct",5),rep("nov",5)),
fuente=c("adwords", "directo", "organico", "redes sociales",
"referral", "adwords", "directo", "organico", "redes sociale
Please keep replies on the list so others may participate in the conversation.
If you have a character vector containing the potential values, you
might look at %in% for one approach to subsetting your data.

When I looked at the data, it has several garbage values need to be

Hi,
I've a data frame with 3 columns: "mes", "fuente", "avg.sessions.duration".
"avg.sessions.duration" is a column containing seconds.
I need you help with:
1.- Help to put these values in "h:m:s" format.

I've found this german page:
It seems like there is substantial finite-sample bias in the MLEs. Either that
or there is some error in your procedure. See attached code.

With a small sample size, n=30, you will have realizations of data where you
will run into difficulties with the MLE of generalized Gamma distribution.
This is mainly due to the `k' parameter. Increase the sample size (e.g., n=50
or 100) and this problem is less likely to happen (but can still

towards code for CART that has been written entirely in R, perhaps that
hasn't made its way onto CRAN.

If you are running these commands from a file using source() then
replacing 'summary(sem)' with 'print(summary(sem))' would help,
as would adding echo=TRUE or print.eval=TRUE to the source()
command.
