Dinamic variables in loop
Hello,
I am a newbie in R and I have a problem.
I want this line:
newMyData <-MyData[!(is.na(col1)) | !(is.na(col2)) | !(is.na(col3)) | !(
is.na(col4)) | !(is.na(col5)),]
write in for loop. The number of col[number] may be different from 3 to 8
Is there any ideas?
Thank you
Laura

Dinamic variables in loop
Dear Laura,
It looks like you want to remove all rows for which each column is NA.
You can to that with the code below.
na.matrix <- is.na(MyData)
all.na.row <- apply(na.matrix, 1, all)
MyData[!all.na.row, ]

turning list into vector/dataframe
Hi,
I have used this command :
resamples<-lapply(1:1000,function(i) sample(lambs,replace=F))
resamples2<-lapply(resamples,Cusum)
to get a list of 1000 samples of my data. The function Cumsum is defined as
follows:
Cusum<-function(x){
SUM<-cumsum(x)-(1:length(x))*mean(x)
min<-min(cumsum(x)-(1:length(x))*mean(x))
max<-max(cumsum(x)-(1:length(x))*mean(x))
diff<-max-min

Plot of a subset of a data.frame()
Hello,
my data.frame is sort of a collection of process values, i.e. huge
run-chart. It consists of a time-stamp in the first column (date as
string), factors in the following columns (used for subset-filtering),
and some process-data columns.
Hereafter, two examples are listed, showing the problems that occour
during print:

Correspondence analysis/optimal scaling with ordinal variable
Dear R specialists,
I have a multivariate statistics question that I want to submit to
the R community (which conveys a very good statistical knowledge).
I need to perform an optimal scaling based on a discrete variable and
an ordinal variable. The discrete variable, Area, defines a
geographical area. The ordinal variable, EducationLevel, describes
the education level of individuals (the

Discriminant plot
Hi Alejo,
According to my knowledge the two plots are different because in the
first one a point belongs to a group depending on its group in the data
whereas in the second plot a point belongs to the group predicted by the
linear discriminant analysis.
I hope somebody will correct me if I am wrong.

NAs are not allowed in subscripted assignments
I'm trying to assign NAs to values that satisfy certain conditions (more
complex than shown below) and it gives the right result, but breaks the loop
having done the first one viz:
new<-c(rep(5,4),6)
for (i in 1:6)
{new[new[i]>5.5][i]<-NA}
gives the correct result, though an error message appears which causes a
break if it's in a loop. If I can get rid of the error message and

Passing colnames to graphics title
Hi,
Just a quick query - if I'm creating a function to produce a number of
histograms per page of output (one per column from a matrix), how can I
pass the column name of the matrix into the title (or indeed to form part
of the x-axis label)?
TIA,
Laura

Further png() question
Ok, I have reinstalled R-1.9.0 and this appears to have fixed the
problems I was having with png(). However, I have a further question
regarding png()
Is it possible to pass a par() argument to the png() command? I am
wanting to produce 4 plots per object, which I normally acheive on an X
window by par(mfrow=c(1,4)). I have tried calling a new plot and setting
par in this way but this has no

Creating 3D Gaussian Plot
Hello,
I requested help a couple of weeks ago creating a dipole field in R but
receieved no responses. Eventually I opted to create a 3d sinusoidal plot
and concatenate this with its inverse as a means for a "next best"
situation. It seems that this isn't sufficient for my needs and I'm really

a question on the use of 'solve'
Dear R users,
I am in trouble using the function
solve(matrix)
in a loop.
When it happens that I have a singular matrix, I get an error message saying
so and the loop stops.
My question is if there in any way to keep on going in the loop.
Thank you in advance,

str and Surv objects
Dear R People:
I used the "Surv" function to produce the following object:
>a <- Surv(1:4,2:5,c(0,1,1,0)) a
[1] (1,2+] (2,3 ] (3,4 ] (4,5+]
>str(a)
Error in "[.Surv"(object, 1:ile) : subscript out of bounds

Why does str(a) give an error, please? Or did I do something wrong?
Thanks in advance.

cluster.stats
Dear list,
I just tried to use the function cluster.stat in the package fpc.
I just have a couple of questions about the syntax:
cluster.stats(d,clustering,alt.clustering=NULL,
silhouette=TRUE,G2=FALSE,G3=FALSE)
1) the distance object (d) is an object obtained by the function dist() on
my own original matrix?
2) clustering is the clusters vector as result of one of the many clustering
methods?

Stacking Vectors/Dataframes
Hello,
Is there a simple way of stacking/merging two dataframes in R? I want to
stack them piece-wise, not simply add one whole dataframe to the bottom of
the other. I want to create as follows:
x.frame:
aX1 bX1 cX1 ... zX1
aX2 bX2 cX2 ... zX2
... ... ... ... ...
aX99 bX99 cX99 ... zX99
y.frame:
aY1 bY1 cY1 ... zY1
aY2 bY2 cY2 ... zY2
... ... ... ... ...

: record which entry in one file doesn't appear in a different file
Hi dear list,
If anybody could help me, it would be great!
I have two files:
File 1 is a list (one column and around 100000 rows)
File 2 is a list with all the names from file one and a few more (one
column and more than 100000 rows)
What I want is to add a column in file 2 that says which name appeared
in file 1 and which doesn't (yes and no would work as a code)

Reconstructing Datasets
Hi,
Is it possible to recreate "smoothed" data sets in R, by performing a PCA
and then reconstructing a data set from say the first 2/3 EOFs?
I've had a look in the help pages and don't seem to find anything
relevant.
Thanks in advance,

Rather new to RoR, so I''m not sure about the terminology and such :-/ .
My question is: how could I know the model which is associated to a

For example:
- controller class is TestController, which is a subclass of
ApplicationController
- associated model class is Test
How could I write some code in a method of ApplicationController to
