Currently in R, constructing a string containing
values of variables is done using 'paste' and can be
an error-prone and traumatic experience. For example,
when constructing a db query we have to write,
paste(SELECT value FROM table where
date =',cdate,')
we are getting null result
Hi,
In Bioconductor, we have something called copySubstitute, which does
what you want, I believe,
x=select @var1@ from @tab1@
copySubstitute(textConnection(x), symbolValues= list(var1=Race,
tab1=ReallyBigTable), dest=stdout())
yields
select Race from ReallyBigTable
you can read in from
The other thing to use is 'sprintf', which would be fantastic in R if it
imputed types based on the format string.
As it is now, for your query you would do:
sprintf(SELECT %s FROM table WHERE date = '%s', column, 2005-10-12)
[1] SELECT column FROM table WHERE date = '2005-10-12'
Which, in my
I tried to install SciViews in R 2.1.0 (on Windows)
and on all machines I get:
bundle 'SciViews' successfully unpacked and MD5 sums checked
Error in sprintf(gettext(unable to move temp installation '%d' to
'%s'), :
use format %s for character objects
how can I solve this problem?

Dear WizaRds,
I am sorry to bother you with a newbie question, but although I tried to solve
my problem using the various .pdf files (Introduction, help pages etc.), I have
come to a complete stop. Please be so kind as to guide me a little bit along my
way of exploring multivariate analysis in

Dear R colleagues,
I am trying to create a new column in a data frame, which converts values
and NA's from another column into binary format. Essentially I need the
NA's to become 1 and the rest to be 0. The code I wrote is returning the
following error message:
Error in if (mort[i, 4] != NA)
See ?is.na

mort[8] - is.na(mort[4])
(If you really want 1/0, add '+ 0' to this expression.)
Testing (in)equality with NA always gives NA. This is discussed in all
good books on S/R, e.g. in MASS (see the FAQ).

I guess you mean `marked for debugging' and not `currently being executed

Debugging is a property
