Hi
Although I posted this in stackoverflow yesterday, I am asking here to get
helps as soon as quickly.
I need help make code for mocking sampling environment. Here is my code
below:
First, I generated mock units with 1000 groups of 100 units. Each row is
considered as independent sample space.
[i]] <- sim.f(p.s=.05, N=1000, sample.size=69, n.sim=500)

Dear R users,
I am trying to simulate surveys and the survey result will be used to
determine the population to be "accepted" or "rejected". With the results,
I would like to calculate cumulative means and plot them to see if a
converged value is as expected. Below is R-code I generated. I need

Hi R-users,
I hope this is not redundant questions. I tried to search similar threads
relevant to my questions but could not find. Any input would be greatly
appreciated.
I want to generate grid with binary values (1 or 0) in n1 by n2 (e.g., 100
by 100 or 200 by 500, etc.) given proportions of
list))

Dear List,
I hope this posting is not redundant. I have several list outputs with the
same components. I ran a function with three different scenarios below
(e.g., scen1, scen2, and scen3,...,scenN). I would like to extract the
same components and group them as a data frame. For example,
pop.i
', space, some wired characters in the middle of names,
etc.). I can send you sample data if you are willing to take a look. Even
though using 'read.delim' works, I am still curious what caused the problem
and potential problem that I may miss.
Thanks again,
SH

Since there was no errors in importing the file into R, I do not have an
idea where to start to fix it. Do you have any suggestion?
Thank you very much in advance,

Dear list:
I would like to extract three letters from first and second elements
in one column and make a new column.
For example below,
> tempdf = read.table("clipboard", header=T, sep='\t')
> tempdf
name var1 var2abb
1 Tom Cruiser16 TomCru
2 Bread Pett2
Very useful comment and helpful website! Many thanks to you!!!

Dear list:
Can I use simple linear regression when I have proportion data for
both dependent and independent variables? Or, should I use beta
regression analysis? Or any suggestion?
Thanks!
