Vary an equation using values from a sequence
I thnk what you want is ?outer. e.g.:
outer(Data -min(Data),value,FUN = "+")
Whether this works for your real task, however, may depend on details and
complexities that you have omitted.
Cheers,

Vary an equation using values from a sequence
It depends a bit on what you plan to do with the results. A loop would be easy and straightforward:
> k <- 1:5
> for(k in 1:5) print(Data - min(Data) + k)
[1] 1 2 3 4 5 6 7 8 9 10
[1] 2 3 4 5 6 7 8 9 10 11
[1] 3 4 5 6 7 8 9 10 11 12
[1] 4 5 6 7 8 9 10 11 12 13
[1] 5 6 7 8 9 10 11 12 13 14
Or you can use sapply() to hide the loop:

How to index the occasions in a vector repeatedly under condition 1? if not, it will give a new index.
Dear all,
Could you please help me how to get the output as I described in the following example?
x<-c(543, 543, 543, 543, 551 , 551 ,1128 ,1197, 1197)
diff<-x-lag(x)
diff
[1] NA 0 0 0 8 0 577 69 0
How to index the occasions in x repeatedly if the diff<15? if diff>=15, it will give a new index.
I want the output be like y.
y<-c(1,1,1,1,1,1,2,3,3)
Thank you so

I need to create new variables based on two numeric variables and one dichotomize conditional category variables.
Hello Everyone,
I have three variables: Waist circumference (WC), serum triglyceride (TG)
level and gender. Waist circumference and serum triglyceride is numeric and
gender (male and female) is categorical. From these three variables, I want
to calculate the "Lipid Accumulation Product (LAP) Index". The equation to
calculate LAP is different for male and females. I am giving both

I need to create new variables based on two numeric variables and one dichotomize conditional category variables.
Well, something like:
LAP <- ifelse(gender =='male', (WC-65)*TG, (WC-58)*TG)
The exact code depends on whether your variables are in a data frame or
list or whatever, which you failed to specify. If so, ?with may be useful.
Cheers,
Bert

Is there any design based two proportions z test?
Hello Everyone,
I was analysing big survey data using survey packages on RStudio. Survey
package allows survey data analysis with the design effect.The survey
package included functions for all other statistical analysis except
two-proportion z tests.
I was trying to calculate the difference in prevalence of Diabetes and
Prediabetes between the year 2011 and 2017 (with 95%CI). I was able to

df$LAP <- with(df, ifelse(G=='male', (WC-65)*TG, (WC-58)*TG))
That will do both calculations and merge the two vectors appropriately. It will use extra memory, but it should be much faster than a 'for' loop.

multiple mounts each varying bitrates
Hi,
Thanks, that helps a lot. I'm trying to get ices2 now to do the
multiple clients and sources, I'll post what I get later today.
Thanks.

Hello,
If anyone is running an Icecast server that serves at least 3 separate
streams each with it's own bitrate can I get a look at your config?
Thanks.

Specifying medoids in PAM?
I am using the PAM algorithm in the CLUSTER library.
When I allow PAM to seed the medoids using the default __build__
algorithm things work
well:
> pam(stats.table, metric="euclidean", stand=TRUE, k=5)
But I have some clusters from a Hierarchical analysis that I would
like to use as seeds for the PAM algorithm. I can't figure what the
mediod argument wants. When I put in the

Is there any design based two proportions z test?
Dear Md Kamruzzaman,
To answer your second question first, you could just use the svychisq()
function. The difference-of-proportion test is equivalent to a chisquare
test for the 2-by-2 table.
You don't say how you computed the confidence intervals for the two
separate proportions, but if you have their standard errors (and if not,
you should be able to infer them from the confidence

I need to create new variables based on two numeric variables and one dichotomize conditional category variables.
Just a minor point in the suggested solution:
df$LAP <- with(df, ifelse(G=='male', (WC-65)*TG, (WC-58)*TG))
since WC and TG are not conditional, would this be a slight improvement?
df$LAP <- with(df, TG*(WC - ifelse(G=='male', 65, 58)))

Quota's with Thunderbird
Hi,
Does anyone know how to get Thunderbird to correctly report the mailbox
quota's? I know Dovecot is correctly enforcing the quotas on the mailbox
when using Thunderbird, but Thunderbird reports that the "server does
not support quota's" when trying to view the usage? Is Thunderbird
expecting something different?
Viewing the mailbox through Squirelmail, the quota's are

Buffer overrun using W2k.
We recently upgraded our NT4 Domain to Win2k.
We use Samba 2.0.7 running on Solaris 2.6 servers.
We are getting buffer overuns in the log files when running
'domain_client_validate' which appears to be due to extensive group
membership (SID History is not being used).
Are there any patches/fixes available to get round this problem?
Thankyou in anticipation.

[EXTERNAL] RE: I need to create new variables based on two numeric variables and one dichotomize conditional category variables.
Yes, that will halve the number of multiplications.
If you?re looking for such optimisations then you can also consider ifelse(G=='male', 65L, 58L). That will definitely use less time & memory if WC is integer, but the trade-offs are more complicated if WC is floating point.

CLI and DNIS presented to Analog extension
My company is based in Australia and we have a need to be able to
present CLI (ANI) and DNIS to an analog extension. Currently our PABX
vendor is saying they can only deliver CLI between the first and second
cadence.
The system will collect calls via an aggregate of ISDN PRI services from
the PSTN and then direct them to the analog extensions in a hunt group
configuration. It is important that
