It may be easy or difficult depending on what your data are like.
GALAXY ACE S 5830 vs S 5830 GALAXY ACE
One easy and reasonably general way would be to divide each such bit
into 4 words and then compare if set 2 contains exactly all words in
set 1 but possibly in different order.
x1 - GALAXY
Hi Tammy,
I think we need more information.
Are the names always four parts?
Does the fix always involve moving two parts from the back to the front?
For that matter, which of the two you gave is correct?
Or does it matter what order the parts are in as long as it's consistent?

Does your dataset have any missing data? (without a reproducible

If it does then you may be fitting the same model to different subsets

Adding on to what Sarah has said, your function appears to limit the

Thanks. Redrawing the points solves it for the minimal example, but
what happens if you have plot(.., type=b) like below?

All,
Relatively new R user so this is probably an easy question to answer.
I am able to generate a cluster for my dataset using hclust() then ploting
the data with plot().
This results in an image with a dendrogram with my sample names along the
bottom. Great!
However, I now need a way to get

If I understand it correctly, something like this will get you what you want.

Hi,
I have 35 data files for reading. I would like get a program for

All are of the type: Dados1.raw, Dados2.raw and so on.

If your previously posted code worked with files all having the same
number of columns, and if your data is read in correctly without the
colClasses argument, then I think the following code should work.
for(i in names){
filepath = file.path(~/Silvano/Dados, paste(i, .raw, sep=))
Hello,
Try the following.
sapply(seq_len(nrow(dat) - 4), function(i){
w - window(dat$value, start = i, end = i + 4)
mean(w[w 0])})
Hope this helps,

i want to know, is there any script in R to measure looping
You could use filter(..., filter=rep(1,5)) to get running sums of length 5
to get your answer. The following calls filter once to get the sum of
the negative values in each window and once to get the number of negative
values in each window, then divides to get the means.

Hello, again.
I forgot, but the subject line also says same axes, not just same axes
scale.
If you want all densities on the same graph, use ?matplot (matrix plot).

My vote for R-Studio. Very elegant design and great functionality. However if
coming from languages like Java and others then eclipse is better. R-Studio
have dedicated section for Mac user which you will find useful.
