I have a data frame with 76 columns of an equal number of species, I want to plot in different plots each species using a loop. However, I want to use the colnames to obtain each plot with the name of each species. Someone could help me with my problem.

I use the following expression in the loop:

title(main=expression(paste("density of",colnames(df))))

I tried with this one:

title(main=expression(paste("density of",colnames(df[,i]))))

Thank you

    Hi Juan - You need to give us some of your data to work with. – Dom Apr 23 '18 at 06:10

for (i in seq_along(colnames(iris))){
  hist(iris[,i],main=paste("density of",names(iris)[i]))
    }
