Creating plots for all variables in a data frame and printing them with the variable name in the main title

Try:

x <- data.frame(A=rnorm(100), B=rnorm(100), C=runif(100))
sapply(names(x), function(i)hist(x[,i], main = i))
Dear all,

 I'm just trying to create plots for all variables in a dataframe (named
 "x") using the following:

 png()
 apply(x,2,hist)

 Just as intended, it produces one plot for each variable. Unfortunately,
 the main title of each graph is "Histogram of newX[,i]" instead of
 "Histogram of name of variable". This makes it impossible to assign the
 graphs to the variables. Is there a way to change this and to make R use
 the correct variable names in the title of the plot?

 Thank you very much,

 Uli
