[R] Passing colnames to graphics title

[Adaikalavan Ramasamy]

Either set the 'main' or 'xlab' in the hist(). See help("par") for more
information on graphical arguments or help("hist").

mat <- matrix( rnorm(1000), nc=5 )
colnames(mat) <- LETTERS[1:ncol(mat)]

for( i in 1:ncol(mat) ){
 hist( mat[ ,i], 
       main=paste( "Histogram of data from column ", 
       colnames(mat)[i] ),  xlab="" )
}
