Hello,
I looked in the R-help but could not find an archive addressing the
following. I would like to convert a character to numeric after reading a
file with RDS extension. After using as.numeric, I checked if it is
numeric. It was not converted. Please help.
Here is my code

function input as variable name (deparse/quote/paste) ??
Hi all
Say I have a function:
myname=function(dat,x=5,y=6){
res<<-x+y-dat
}
for various input such as
myname(dat1)
myname(dat2)
myname(dat3)
myname(dat4)
myname(dat5)
how should I modify the 'res' line, to have new informative variable name
correspondingly, such as
dat1.res
dat2.res
dat3.res
dat4.res
dat5.res
stored in the workspace.
This is only an example of a complex

Subsetting year range
Hi,
I have a panel data set that I am trying to subset. I am trying to keep
values for years >=1960.
The full set is from 1940 to 2000.
I tried a few things, but none worked. Here are a couple that I am trying to
use.
TableAPS1 <- subset(TableAP, year => 1959)
TableAPS1 <- TableAP[ which(year > 1959),]
It would be really nice if someone can point out what I am doing wrong

Help for Fisher's exact test
Hi, R-help,
I have a group of data from RNA-seq want to be analyzed by Fisher's
exact test in R. I want to compare the significant difference of about
30,0000 individuals in two different samples, and I have no idea how to use
R, so could you please give me some suggestions or the scripts for
Fisher's exact test? Thank you very much.

First value in a row
Hi.
This is likely a trivial problem but have not found a solution.
Imagine the following dataframe:
Lat Lon x1 x2 x3
01 10 NA NA .1
01 11 NA .2 .3
01 12 .4 .5 .6
I want to generate another column that consist of the first value in
each row from columns x1 to x3. That is
NewColumn
.1
.2
.4
Any input greatly appreciated,
Thanks,

Function that is giving me a headache- any help appreciated (automatic read )
note: whole function is below- I am sure I am doing something silly.
when I use it like USGS(input="precipitation") it is choking on the

b <- ddply(precip.1$precipitation, .(precip.1$gauge_name), cumsum)
DF.precip <- precip.1
DF.precip$precipitation <- b$.data

error calling Winbugs using R2WinBugs to run a multi-level model
Dear all,
I'm calling Winbugs (1.4.3) through R2WinBugs (2.1-18 coda_0.14-7) to

with the log only displaying 'check('.
I will paste the trap with session info below; I'd be very grateful
for any ideas.
Couple of leads:

How to replace numeric value in the column contains Text (Factor)?
Hi R user,
Would you mind to help me on how I can change a value in a specific column
and row in a big table? but the column of the table is a factor (not
numeric).
Here is an example. I want to change dat[4:5,3]<-"20" but it generated NA>
do you have any suggestions for me?

summing 15 minute precip data to daily
Hi all,
i'm sure there is an easy way to do this, but i'm stumped, so any help would
be appreciated.
i have a single column of data for precipitation every 15 minutes over a
year. i want to sum the precip to daily data.
so the first 96 records = the first day, the second 96 records = the second
day, and so on....
is there a way to write a for loop that would sum the data to daily, and

How to replace numeric value in the column contains Text (Factor)?
The simplest would be to convert precip to character and then back to a factor if you really want it to be a factor. This will also remove the levels that no longer exist.
str(dat)
# 'data.frame': 5 obs. of 3 variables:
# $ Sites : Factor w/ 5 levels "Site1","Site2",..: 1 2 3 4 5
# $ temp : num 14 15 12 12.5 17
# $ precip: Factor w/ 5 levels

combination xyplot and barchart?
Dear R community,
I am having trouble determining how to create the graph I want
utilizing my relatively limited knowledge of R. So far I have been
using the lattice library to create most of what I need.
The dataset (enviro) consists of 2 variables (Temp and Precip) for each
Day of a 2-yr period (Year). I wish to display Temp and Precip along
the y axis plotted by Day on the x axis to allow
