Package "demography" - calculating quintiles of survival probabilities
Hi,
I am using the package "demography" from Rob Hyndman for the
Lee-Carter-Model. It is an amazing powerful tool but I am struggling with
one issue:
*I want to compute different quintiles for the cumulative survival
probability derived from the Lee-Carter-Forecast (e.g. the 50%-quintile,
75%-quintile and 99%-quintile) for the next 10 years. *
I am sure the package possess this

conditional weighted quintiles
Dear All,
I am economist and working on poverty / income inequality. I need descriptive
statitics like the ratio of education expentitures between different income
quintiles where each household has a different weight. After a bit of
google search I found 'Hmisc' and 'quantreg' libraries for weighted quantiles.
The problem is that these packages give me only weighted quintiles;

Hi All:
Greetings, and best wishes from the festive times here at Kolkata, India -- the time of Durga Puja celebrations.
I seek your advice as I try plotting lines for my data. The problem:
I have created a dataframe that looks like this (name: myFrame):

intercept. But I`m getting the following error for the 'Baci' variable:

Creating quintiles on monthly basis
Hi,
I am trying in R to indicate in which quintile a value of a variable is for
every month of my data frame in this case based on volatility. For each
month I want to know for each stock if it is in the most volatile quintile
of if it is in one of the others.
So far I have come up with the following function (see below).
Unfortunately, the function only works in some cases and often gives the

Hi,
I have a mysql table with fields userid,track,frequency e.g

I need to turn my 'frequency' table into a rating table (it's for a

Problem using with panel.average in Lattice package
Hi,
I'm having a problem getting the panel.average function to work as I
expect it to in a lattice plot. I wish to draw lines between the
averages of groups of y-values at specific x-values. I have created a
dataset below which is similar to my real data. I also show an example
of using panel.loess in place of panel.average; it performs in a
manner similar to what I want panel.average to do

Converting "factors" to "numeric" in a dataframe
I am currently trying to write a program that minimises the amount of work
required for “auditable” qPCR data. At the moment I am using an Excel (.csv)
spreadsheet as source data that has been transposed to the column format
required for R to read. Unfortunately, this means I have* *to manually
confirm the whole data set prior to doing any analysis, which is taking a
considerable amount of time!

From NUM to INT
Can you explain why you need them as 'integer', A floating point
representation can hold a value upto ~4.5e15 as an "integer" keeping the
precision that you might need.
