Importing multiple worksheets from one Excle/ csv file into R
Dear R experts,
I am trying to import some data from some Excle files into R. My Excle file
contains about 50 sheets.
One solution I can think about is to convert my Excle file into csv file
first and then load data into R using 'read.csv'.
But it seems to me that 'read.csv' only supports reading one sheet (or 'one
file') each time, so that seems I have to create 50 csv

Placing a column name in a variable XXXX
Hi everyone,
How does one place an object name (in this case a vector name) into another
object (while essentially masking the values of the first object?
For example:
> JOBSAT<-rnorm(40)
>
> CI<-function(x,alpha){
+ result<-cbind(x,mean=mean(x),alpha)
+ print(result)
+ }
> CI(JOBSAT,.05)
I want this to return:
Variable mean alpha
JOBSTAT 0.02844131 0.05

Using !is.na() in a HAVING clause in sqldf() XXXX
Hi everyone,
I have the following:
sqldf("select Premie,count(tpounds) N,avg(tpounds) Avg_Weight,
stddev_samp(tpounds) StdDev
from children
group by Premie
having !is.na(Premie)")
sqldf() does not like the !is.na(Premie) specification. How does one
exclude a "missing" group in an aggregated query using sqldf()?
Thanks!

Obtaining the internal integer codes of a factor XXXX
Hi everyone,
I understand the process of obtaining the internal integer codes for
the raw values of a factor (using as.numeric() as below), but what is
the best way to obtain these codes for the levels() of a factor (since
the as.numeric() results don't really make clear which code maps to
which level)?

Using a mathematical expression in sapply() XXXX
Hello everyone,
I have the following call to sapply() and error message. Is the most
efficient way to deal with this to make sum(!is.na(x)) a function in a
separate line prior to this call? If not, please advise.
N.Valid=sapply(x,sum(!is.na(x)))
Error in match.fun(FUN) :
'sum(!is.na(x))' is not a function, character or symbol
Thanks!

Convert components of a list to separate columns in a data frame or matrix XXXX
Hello everyone,
What is the most efficient & simpliest way to convert all components of a
list to separate columns in a matrix?
Is there an easy way to programmatically "pad" the length of the resulting
shorter character vectors so that they can be easily combined into a data
frame?
I have the following code that stores the 2 compoents (of differing
lengths) in the same character
