Hi,
I am trying to use system() to run some command in OS. such as
system("cmd 'a\tb')
however, it alway runs
cmd 'ab'
instead of
cmd 'a\tb'
How can I prevent system to interpret 'a\tb' to 'ab'?
Thanks

Yes. I forgot to escape the escape. Thank you so much.

Dear all,
I am now writing a R library. After I build it in Windows *R CMD INSTALL
--build --compile-both foo.tar.gz*, I get a file foo.zip. foo.tar.gz is the
source file tarball. When I tried to install the package in R (
*install.packages("foo.zip")*, or choose the zip file from menu
package/ins
Hi,
I am now writing an R package LFSpro. I build it for both Mac OS and
Windows.
For Windows, the binary package name is LFSpro_1.0.3.zip. It can be
installed into R successfully. But when I changed the name to
LFSpro_1.0.3.Windows.zip, an error occurred:
Error in read.dcf(file.path(pkgname,"DE
I see. Thanks a lot.

Hi,
I added two sliderInput into the app with package "shiny": sliderA and
sliderB. The values in the two sliders are correlated. If I change sliderA,
I used updateSliderInput to update the value in sliderB. And also If I
change sliderB, I used updateSliderInput to update the value in slideA.

I see. Thanks a lot for your help.

I thought '+' was defined in a more basic level. I usually use CPP. R is
very different from CPP in many basic concepts.

David gave a great solution. I think it is better to start from 0 to min(M)
instead of from min(M[c(1,3)]) to avoid negative values in the table. If
the minimum is in M[1] or M[3], a = 1:min(M). Otherwise, d=1:min(M).

You can use the following command:
tmp <- get(foo)
save(tmp,file=paste(foo,'.rData',sep=''))

you can get a new data frame by
merge(qpiso, qplegit, all.x = TRUE, all.y = TRUE, by = "iso" )
Take the subtraction on the new data frame.

For the t-test, you used the two-tailed t-test. It is the default. Here I
think you should set alternative="less" in the t.test function.

Did you add xaxt = "n" in the plot function?
Try the following:
plot(x,y, xaxt = "n")
axis(1, at = c(14, 20),labels = c("14h", "20h") )
