Hey,
i have a question about how to reorganize a data frame in the easiest way.
my example: what would be the easiest way to bring a data.frame such like this:
nr height age Seed
1 1 4.51 3 301
2 15 10.89 5 301
3 29 28.72 10 301
4 43 41.74 15 301
5 57 52.70 20
A different approach is to use order() to sort
first by row number and then break the ties by
value. It is quick when there are lots of short
rows.
f1 - function (x)
+apply(x, 1, function(row) sort(row, decreasing = TRUE)[2])
f2 - function (x)
+ -apply(-x, 1, function(row)
And I hit the send button before adding the timings for
when there were lots of columns and few rows. f3 changes
from the best to the worst in this case. There is rarely
one most efficient function for all datasets.
x - t(x)
benchmark(r1 - f1(x), r2 - f2(x), r3 - f3(x), r4 - f4(x),
try this:
x
nr height age Seed

Hi all,
I tried to plot the density curve using the data from simulation. I am
sure that the data should be exponentially distributed, but the plot
of density curve always starts from (0,0) which is not the case for
exponential distribution. Is there any way around this, to keep the
In barplot for degree distribution x-axis is not seen.
See the example below
g = barabasi.game(500, 0.4)
dd1 = degree.distribution(g)
plot(dd1, xlab=degree, ylab = frequency)
whereas barplot doesnot have any x-axis
barplot(dd1, xlab = degree, ylab = frequency)
Please see the figures
Greetings from Rio de Janeiro, Brazil.
I am looking for advice / references on binary logistic regression
with weighted least squares (using lrm weights), on the following
context:
1) unbalanced sample (n0=1, n1=700);
2) sampling weights used to rebalance the sample (w0=1, w1=14.29); e

Hey Everyone!
I´m a quite new R user .. I found a problem that I'd like to share with you
and help me find a solution.
I have a large txt. file which I opened with read.table command, and what I
understood from many R manuals is that I have a kind of matrix readed with
read.table,
I've used
I would generally use the coef() extractor function if
it's available (and it is for nls()). ?nls has an example:
coef(summary(fm1DNase1))
I knew about coef() on model objects, but I did not know it had
methods for their summaries. What wonderful information!

Is this what you were looking for as output. You did not show what
the output would look like:

How do I extract the standard error of the parameter estimates?
Also, if I would like to add two parameters together (x+y), can I use this
equation to calculate the new standard error?:
x = parameter 1
y = parameter 2
Hi:
Try this (and note the use of vectorization rather than a loop):
rate - 3
dta - -log(1 - runif(1000))/rate
hist(dta, nclass = 30, probability = TRUE)
x - c(0.001, seq(0, 3, by = 0.01))
lines(x, dexp(x, rate = 3))
This is the difference in timings between the vectorized and iterative
methods

It is not clear to me precisely what your blocking rules are (e.g., where
should matrix[4,4] go, is matrix[5:7,5:7] to be considered as a different block
to matrix[8:10,8:10]). Also, what happens if there is an isolated 1 (e.g., in
location matrix[9,6])? However, I imagine
Hi:
Firstly, you should have mentioned that you were using the igraph
package; with over 2700 R packages available on CRAN, it's
unreasonable to expect folks to know to which package a particular
function resides, but you may not have been aware of that fact. It
turns out that dd1 is a numeric

Sorry David, I understand what you mean but could you help with how it would

Maybe this can help get you started. Reading your data into a matrix m,
m - structure(c(1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0,
