Dear List: Below is how I specify an axis: axis(2, at=c(0.00005, 0.0005)) R displays the numbers in scientific notation. What argument/parameter should I use to tell R to display the numbers as specified rather than in scientific notation?> version_ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 5.1 year 2007 month 06 day 27 svn rev 42083 language R version.string R version 2.5.1 (2007-06-27)

I believe the argument to format is "scientific" i.e. axis(2, at=at, labels=format(at, scientific=FALSE)) Best regards, Francisco Duncan Murdoch wrote:> On 9/26/2007 11:24 AM, Jacques Wagnor wrote: >> Dear List: >> >> Below is how I specify an axis: >> >> axis(2, at=c(0.00005, 0.0005)) >> >> R displays the numbers in scientific notation.

Here setting a small positive value of options(scipen) (e.g. 2) gives floating-point notation as in> at <- c(0.00005, 0.0005) > options(scipen=2) > as.character(at)[1] "0.00005" "0.0005"> axis(2, at=at, labels=as.character(at))would do the job (and in many similar cases).> > Best regards, > > Francisco > > Duncan Murdoch wrote: >> On 9/26/2007 11:24 AM, Jacques Wagnor wrote: >>> Dear List: >>> >>> Below is how I specify an axis: >>> >>> axis(2, at=c(0.00005, 0.0005)) >>> >>> R displays the numbers in scientific notation.
