I tried to plot the attached dataframe with the following command. plot(inclino.06.1.r00.time.select.transpose[,1],inclino.06.1.r00.time.select.transpose[,2]) The first column is in date format, second is numeric. The plot...
In a loop, I compose the name of a csv file using paste, then read it (e.g., dataset1.csv, dataset2.csv, etc). The name of the dataframe assigned to the imported csv is also composed with paste (e.g...
Have you tried max()? i.e. plot (D10$Part.P ~ D10$Klorofyll,pch=16,log = "xy", xlab = ("Chla"), ylab = ("POP"), ylim = c (0, max(D10$Klorofyll))) helene frigstad wrote: > > Hi, > > is there any way to set the ylim range from...
Rich, Distances can be interpreted as degrees of similarity. In your dataset, it means that the observation in 2004 is more similar to 2011 than 2013. You can visualize distances using distance-based clustering (http://www.statmethods.net/advstats/cluster...

Hi Rich, It is not clear whether you need a supervised or an unsupervised model. Clustering is unsupervised: it will classify compositions in hierarchical groups regardless the label (countries, regions). If this is what you intend, you might compute the...
Hello Gentlemen, All of your answers were helpfull. Indeed, 'as.is=TRUE' or 'stringsAsFactors=FALSE' avoid importing as factors, as it did when I imported the table without specifying anything. However, data frames will not allow different datatypes within a...
Hi Rich, Filzmoser et al. (2009) wrote that "Some measures like the standard deviation (or the variance) make no statistical sense with closed data [...]". They also wrote that "If Euclidean geometry is not valid, the arithmetic mean is quite likely...
