[R] "rounding" to a number that is LOWER than my number
Hello! What function would allow me to "round" down, rather than up? For example, x<-1.98 I'd like to get 1.9 - rather than 2.0. Reason - I am creating a minimum for an axis for a plot, and I need it to be lower than x (which, in turn, is the lowest number already). Thank you! -- Dimitri Liakhovitski marketfusionanalytics.com

In other words, I am looking for something like floor, but more flexible - as it should allow me to: turn 1.98 into 1.9 or turn 298 into 290, etc. Dimitri On Fri, Sep 16, 2011 at 12:28 PM, Dimitri Liakhovitski <dimitri.liakhovitski at gmail.com> wrote:> Hello! > > What function would allow me to "round" down, rather than up? > For example, x<-1.98 > I'd like to get 1.9 - rather than 2.0. > > Reason - I am creating a minimum for an axis for a plot, and I need it > to be lower than x (which, in turn, is the lowest number already). > Thank you! > > -- > Dimitri Liakhovitski > marketfusionanalytics.com >-- Dimitri Liakhovitski marketfusionanalytics.com
This is easy to do (e.g. divide by the appropriate power of 10, use floor, multiply the power of 10), but you are going about it in the wrong way. See the "xaxs" component of the ?par argument list for the right way. -- Bert On Fri, Sep 16, 2011 at 9:28 AM, Dimitri Liakhovitski < dimitri.liakhovitski@gmail.com> wrote:> Hello! > > What function would allow me to "round" down, rather than up? > For example, x<-1.98 > I'd like to get 1.9 - rather than 2.0. > > Reason - I am creating a minimum for an axis for a plot, and I need it > to be lower than x (which, in turn, is the lowest number already). > Thank you! > > -- > Dimitri Liakhovitski > marketfusionanalytics.com > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >-- "Men by nature long to get on to the ultimate truths, and will often be impatient with elementary studies or fight shy of them.
