I was trying to plot some data in R. I used the following code to draw a loess
fit and got the output as
>?lines(lowess(log(abs(t(res))), log(abs(t(synthesised)))), col="red")
Error in lowess(log(abs(t(res))), log(abs(t(synthesised)))) :?? NA/NaN/Inf in
foreign function call (arg 1)
Then I thought to use Limma package for background correction. Is it a right
choice ?
However, I installed Limma using
> source("http://www.bioconductor.org/biocLite.R";)
> biocLite("limma")
> biocLite("statmod")
> library(limma)
and then used the commands which generated the error as follows --
> system.time(fit <- loessFit( log(abs(t(res))), log(abs(t(synthesised)))))
Error in loessFit(log(abs(t(res))), log(abs(t(synthesised)))) :
? binary operation on non-conformable arrays
Timing stopped at: 0.57 0.06 0.64 NA NA
> system.time(fit <- plotPrintTipLoess( log(abs(t(res))),
> log(abs(t(synthesised)))))
Error in 1:layout$ngrid.c : NA/NaN argument
In addition: Warning messages:
1: In object$printer :
? $ operator is invalid for atomic vectors, returning NULL
2: In object$M : $ operator is invalid for atomic vectors, returning NULL
3: In object$A : $ operator is invalid for atomic vectors, returning NULL
4: In object$M : $ operator is invalid for atomic vectors, returning NULL

6: In layout$ngrid.c :

Can someone please?tell me where the problem is and?what could
