Standard variance / devistion clarification
Dear gurus,

p-values in agricolae pearson correlation
I have used the correlation analysis (pearson) in the agricolae package to
analyse my data and got unexpectedly low p-values (therefore making many
more highly significant correlations in my data than I had expected). I am
wondering if the p-values given should be subtracted from 1 to give the real
p-value, because for each variable compared against itself has a p-value of
1 and I thought it

My name is Iut Tri Utami. i am beginning user. I have a problem about
generate data in R. It consists of one disk generated by a Gaussian N(0,

problem with geom_point in ggplot using a different column
I want to draw boxplot where the geom_points are displayed based on
"ERBB2.MUT" subset and they should be displayed in the right box (based
both on the "ERBB2.2064" field and "ERBB2_Status").
However, given my command I currently only see "red" points corresponding
to "MUT" subset in one straight line corresponding to only "ERBB2.2064"

Creating Multiple Repeating samples and Cross Correlating them.
I'm having a lot of trouble getting this done and nothing I've written has
been remotely successful. Basically I have about 64 binary data sets stored
as vectors, with 72900 entries in each. I am not very familiar with cross
correlations, but I was advised that I should create 1000 randomized date
sets (used sample() for that) to use as a control, then compare the cross
correlation of my

I'm afraid.
Thanks!

How to Compare the median to the mean?
Okay, so I have a homework projecr for R, and we had to input the following
link as some sort of data:
nb10 <- read.table("http://www.adjoint-functors.net/su/web/314/R/NB10").
Afterwards, we have to use
fivenum(nb10) to find max, min, quantiles, and sd, but I'm okay with this.
The next question is where I'm stuck. The question is as follows;

strftime - Dates from Excel files
Hi
I have many excel files were the Date field was not declared as date,
so the dates look like this: 1/2/1978
I know that the format is day/month/year
How can I make R change this to Date format?
If I use strftime, I get wrong dates:
dataset=c("1/2/1978")
strftime(dataset,"%d/%m/%Y")
"19/02/0001"
Thanks in advance.
