If you want the column names but not the data frame name, then you could do:
with(dat, myPlotFun(Col1, Col2)) Pat On 17/01/2013 20:07, Patrick Burns wrote:
You are thinking that 'names' does something different than it does. What you seem to be after is the deparse-substitute idiom: dat <- data.frame(Col1=1:10, Col2=rnorm(10)) myPlotFun <- function(x, y) { plot(y ~ x, xlab=deparse(substitute(x)), ylab=deparse(substitute(y))) } myPlotFun(dat$Col1, dat$Col2) Pat On 17/01/2013 18:53, mtb...@gmail.com wrote:Hello R-helpers, I have run the following line of code: x<-dat$col and now I would like to assign names(x) to be "dat$col" (e.g., a character string equal to the column name that I assigned to x). What I am trying to do is to assign columns in my dataframe to new objects called x and y. Then I will use x and y within a new function to make plots with informative axis labels (e.g., "dat$col" instead of "x". So, for example, I would like to plot (y~x,xlab=names(x)) and have "dat$col" printed in the x-axis label. I can do this all manually, by typing names(x)<- "dat$col) but I'd like to do it with non-specific code within my function so I don't have to type the variable names manually each time.
