Mangrove data

I have data from a volunteering project on mangroves that I need written into R and imported into a csv file to compute the mean and standard error of the average total mangrove tree density for both method types (plot and pcqm). I also need a column plot made from the data that shows the two means, error bars, and standard errors. I also need a one-way ANOVA to test the significant difference of the total density for both methods. I also need a leveneTest for homogeneity of variance and a shapiro.test for normality
