Dear Sir,

I do appreciate your views. Yes even I was also aware about the non
clarity in the question. Actaully, I have a large data having lots of
data of low magnitude and few of very high magnitude. In order to

can you explain what is low or high magnitude? Or better to use

dput(head(yourdata, 20))

and copy the result so as we might see better what you mean.

Just a guess, from your previous post are you iterested in some summary for your data?

x<-c(6,6,5,6,4,6,8,4,6,6,6,3,4,6,5,7,7,4,3,5,5,5,3,6,7,4,4,7,4,3,4,6,4,6,5,4,4,7,6,8,5,6,5,5,8,2,3,5,7,5)
table(x)

x
 2  3  4  5  6  7  8
 1  5 11 11 13  6  3

Cheers

analyse the same, some very senior person in the office suggested me

to

assign weights to these obervations.

Problem is this senior person is on office tour travelling into
Australia and unfortutely I can't even think of reverting to him owing
to his seniority. I tried to find through some R libraries if I can

get

something about sample weights.

But as you have pointed out, yes my question is too vague and feel
really sorry about the same. And I have recently started with R
language hence I am trying to learn some basics about R. Thanks for
pointing the difference between data.frame and vector.


Thanks again for your response.

Regards

Amelia

If you have a clear idea what meaning those weights have (?) in the
context of a specific calculation (?), and you know what the weights
are (?), then it is usually trivially easy to do in R. However,  your
question is vague on all of those points, so offering you a solution
seems like an invitation for you to mis-use any particular solution
offered. Please try to clarify what you are doing that "weights" will
help with, and yes, there may just be a weights argument to the
function that does that analysis that we can point you to.

You also are unclear what the difference between a data frame and a
vector is... if it helps, a data frame is a list of vectors (typically
referred to as "columns") all with the same length...  your "mydat" is
a vector, not a data frame.

Dear R Forum

I have a data.frame as


mydat =
c(6,6,5,6,4,6,8,4,6,6,6,3,4,6,5,7,7,4,3,5,5,5,3,6,7,4,4,7,4,3,4,6,4,6

,

5,4,4,7,6,8,5,6,5,5,8,2,3,5,7,5)

Is there any library or way in R to allocate weights to these values?
Actually I am having a large data, but for illustrative purpose, have
considered just a small part of the same.

Regards

Amelia
