vec2sm( r, diag = FALSE, order=rr )
Next time please make an effort to post using plain text format, as your
HTML-formatted email got rather messed up coming through this plain-text

You might find a reading of The R Inferno informative on the subject of F vs.
FALSE.

I like to compose a symmetric matrix in the pattern as shown below (for 3 x
3 and 4 x 4). For a symmetric matrix of order 5, the result does not seem
right. Help? It is possible to write a two-level do loop for the task, but
I suppose that is less efficient.

Not sure what C+ software is, but with regard to C or C++ compilers the short
answer is probably not. The true answer is that it may depend on your
unspecified operating system and on what packages you want to use.
If you are on windows you can install most packages from zip files with no

Hi kalyan,
It is a bit difficult to work out what you want to do. However, there are
some things I can suggest. The gsub function is useful for changing strings
not assigning new values. If you want to delete a column of a data frame if
there are any NA values, you first want to check for NA values
Inline beow.

Hi,
I am new to R and learning the basics.so i came to know that data frame can
store any data type as oppose to matrix which stores only numeric.My
question is
1.)How to replace a particular pattern with new pattern in data frame.I
tried something like
x = as.data.frame(gsub(".*LINK.*","NA",file))
Dear Sirs,
just wanted to check whether C+ or C++ software is required to be in the

By the way, I have to say that I am dealing with missing values and that is why
I am using clara or I may use pam, as kmeans (which is very good at dealing
with large datasets) cannot handle missing values.

Clara uses the Euclidean distance.
Why you get different results can only be said if you provide a reproducible
code example for both what you did in clara and what you did "manually".
Best wishes,

I do not think this is quite true. When the medoids are not specified,
pam/clara looks for a good initial set (build phase) and then finds a local
minimum of the objective function (swap phase). Both pam/clara and kmeans can
find local minima that are not the global minimum. If the build phase i
Each observation is assigned to the closest medoid, a single observation. An
observation that is between two medoids will be assigned to the closer one even
if its distances to members of the other cluster are closer on average (but the
medoid of that cluster is slightly farther away). If the cl

Oh, thanks Peter, good example for Mac, but indeed not working on Windows.
For a completely cross-platform solution (that is, including Windows which
is what Zahra wants), I believe shiny is the right tool.
So Zahra, if you want to use shiny, you need to look at their own
tutorials, step by step,
Sorry, but please do not multiple post. That's spam.
This is a list about the R programming language, not about statistical
methods. While there is often some overlap, your questions are entirely
statistical and therefore OT here( at least imo). Try a statistical list
like stats.stackexchange.com
