R help - Feb 2011 - Simple Boxplot Question- unexpected string constant error

Hi everyone,

Sorry for the newbie question but whenever I enter the following code into r
it gives me an  unexpected string constant in
"boxplot(Abs~Conc,ylab='Absorbency',xlab'Ethanol(%)'"
error. I have tried
everything to eliminate it and have searched these forums to no avail, can
anyone tell me what to do to allow r to generate my boxplot for me? Here is
my code:

A=c(0.37,0.38,1.1,1.1,0.65,0.61,0.56,0.74,0.71,0.60)
B=c(0.66,0.63,0.85,0.9,0.8,0.9,0.8,0.8,0.41,0.49)
C=c(1.2,1.2,1.4,1.35,1.2,1.2,1.35,1.75,0.86,0.8)
D=c(1.1,1.2,1.2,0.8,1.1,0.85,0.94,1.4,0.88,0.63)

Abs=c(A,B,C,D)
Conc=c('0','0','0','0','0','0','0','0','0','0','20','20','20','20','20','20','20','20','20','20','30','30','30','30','30','30','30','30','30','30','40','40','40','40','40','40','40','40','40','40')

boxplot(Abs~Conc,ylab='Absorbency',xlab'Ethanol(%)')

Hi:

Put an equals sign between xlab and '
