Adding two or more columns of a data frame for each row when NAs are present.
...e result for each row in
mySum? NA should be treated as a 0. Please, note, I do not want to sum all
the columns, as I think rowSums would do, just the selected ones.
Thanks for your help.

Compare data between two groups/countries on 5-point Likert scale questionnare?
...on't know which is the best way to analyse my data
after trying to find a solution for days. Basically, my questionnaire is
structured in this way:
Q1 - Q5: statements on environment-oriented CSR
Q6 - Q10: statements on workplace-oriented CSR
Q11 - Q15: statements on community-oriented CSR
Q16-Q20: statements on market-oriented CSR
All of the statements are 5-pt Likert questions. I initially planed to
compare the grouped mean values for each of the above section but I know
that it's not scientific. So can someone give me any advice on which kind of
tests is most suitable for my research...

reemplazar valores en texto según condiciones
Buenas,
Se me hace raro que la función no admita un parámetro para eso.
Una opción es hacerlo en dos pasos:
P1: Reemplaza p10, p20, ... por algo como q10, q20, ...
P2: Haz el reemplazo que quieres.
Igualmente puedes hacer el reemplazo que haces y en un segundo paso reemplazar p10_integra_datos por p10_cuales_rep, ...
Un saludo, Manuel.

reemplazar valores en texto según condiciones
Hola,
Algo que me está pasando con esta función es lo siguiente:
A "p1" lo tengo que reemplazar por "p1_integra_datos" y a "p10" por
"p10_cuales_rep", pero como p10 contiene p1, y así pasa con otras preguntas
(p2 y p20, por ejemplo),
me los reemplaza en ambas, cuándo lo que busco es otra cosa.

Having trouble converting a dataframe of character vectors to factors
R Experts,
I have a dataframe made up of character vectors--these are results from survey questions. I need to convert them to factors.
I tried the following which did not work:
scs2<-sapply(scs2,as.factor)
also this didn't work:
scs2<-sapply(scs2,function(x) as.factor(x))
After doing either of above I end up with
>str(scs2)

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
