two plots on the same axis
Good morning. I wish to plot two data on the same axis. I tried plot(x,y,
type = "l") for the first and tried to use lines or points(x,y, lty = 2, col
= 4) to add or plot the second data on alongside the first. However, what I
got was not encouraging.
I have attached the two data and would be pleased if anybody could be of
help.
Thank you
Best regards

Writing audio files (.wav) in a different directory
Hi.
I'm trying to export a .wav file using the writeWave function from tuneR
package in a different folder than the default getwd().
After reading through the manuals of some audio packages I couldn't figure
it out.
I'm picking one 3-hour .wav file and asking the function to take a sample
of 1 minute (from minute 100 to minute 101 of the 3-hour file) and saving
it in an object

implicit loop for nested list
I would use replicate() to do an operation with random numbers repeatedly:
```
mysim <- replicate(10, {
two.mat <- matrix(rnorm(4), 2, 2)
four.mat <- matrix(rnorm(16), 4, 4)
list(two.mat = two.mat, four.mat = four.mat)
})
```
which should give you a matrix-list. You can slice this matrix-list
just like normal, then cbind it in one step:
```

loop of quartile groups
Greetings R users,
My goal is to generate quartile groups of each variable in my data set. I
would like each experiment to have its designated group added as a
subsequent column. I can accomplish this individually with the following
code:
brks <- with(data_variables,
cut2(var2, g=4))
#I don't want the actual numbers, I need a numbered group

warning with cut2 function
Dear r user,
please find my attached sample of the dataset i? am using to create a crosstable and eventually plot a histogram from the output.
I am using? the cut2 function to create bins, about 7 of them using the code after reading the data:
cluster <- cut2(cross_val$value, g=7)
I get the warning:

cut2 error
To R users,
I am trying to use cut2 function from the 'Hmisc' library. However, when I
try and run the function on the following variable, I get an error message
(displayed below). I suspect it is because of the NA but I have no idea
how to address the error. Many thanks to any insights.

Improving effeciency - better table()?
Hi,
I've been running some simulations for a while and the performance of R
has been great. However, I've recently changed the code to perform a sort
of chi-square goodness-of-fit test. To get the observed values for each
cell I've been using table() - specifically I've been using cut2 from
Hmisc to divide up the range into a specified number of cells and then

cut2 once, bin twice...
Hello,
I'm using the Hmisc cut2 function to bin a set of data. It produces bins
that I like with results like this:
[96,270]:171
[69, 96): 54
[49, 69): 40
[35, 49): 28
[28, 35): 14
[24, 28): 8
(Other) : 48
I would like to take a second set of data, and assign it to bins based on
factors defined by my call to cut 2.
Does anyone know how I can do this?
Thank you,
-S

Matrix to data frame conversion
I have a matrix which I wanted to convert to a data frame. As I could not
succeed and resorted to export to csv and reimport it again. Why did I fail
in the attempt and how can I achieve what I wanted without this
roundabouts?
The original matrix:

aggregating along bins and bin-quantiles
Dear all,
I would like to aggregate a data frame (consisting of 2 columns - one
for the bins, say factors, and one for the values) along bins and
quantiles within the bins.
I have tried
aggregate(data.frame$values, list(bin = data.frame
$bin,Quantile=cut2(data.frame$bin,g=10)),sum)
but then the quantiles apply to the population as a whole and not the
individual bins. Upon this

what does cut(data, breaks=n) actually do?
Hello,
I'm trying to bin a quantity into 2-3 bins for calculating entropy and
mutual information. One of the approaches I'm exploring is the cut()
function, which is what the mutualInfo function in binDist uses. When it's
called in the format cut(data, breaks=n), it somehow splits the data into n
distinct bins. Can anyone tell me how cut() decides where to cut?
Thanks,

cannot assign dimnames
Dear list,
If anyone knows how to assign dimnames to matrices or arrays I would be most
grateful for help. I've tried various permutations of likely-looking code
but get error messages every time. I could find no example in the
documentation.
Many thanks,

cut and re-factor data
Hello R-users,
I have a data frame with a factor of ages in 5 year increments, and various
count data for each age group. I only have this summary information in R at
the moment.
I want to create a new factor that aggregates the age factors if the
existing factors have insufficient counts. Then I can use aggregate to
build a new data set.
I figured out I can get the cut values I want using cut2

Position of legend box
Good morning to you. I have about 4 different lines in one plot. I have used
legend to indicate the colour of each plot. But the box contain the legend
covers part of the lines thereby blurring the legend. There are some spaces
in the plot that are empty and large enough to accommodate the legend box.
If there a command I could use to set the position of the legend myself.

rank with uniform count for each rank
Hello,
What is the best way to get ranks for a vector of values, limit the range
of rank values and create equal count in each group? I call this uniform
ranking...uniform count/number in each group.
Here is an example using three groups:
Say I have values:
x = c(3, 2, -3, 1, 0, 5, 10, 30, -1, 4)
names(x) = letters[1:10]

survfit using quantiles to group age
I am using the package Design for survival analysis. I want to plot a
simple Kaplan-Meier fit of survival vs. age, with age grouped as
quantiles. I can do this:
survplot(survfit(Surv(time,status) ~ cut(age,3), data=veteran)
but I would like to do something like this:
survplot(survfit(Surv(time,status) ~ quantile(age,3), data=veteran)
