correlation plot in color
Hola Manuel: As you have loaded the ggplot2 package, one simple way to do the correlation plots (one at the time though) is, for example for your pair of variables EMF and your first MSD axis: ggplot(data = Libro) + geom_point(mapping = aes(x = EMF, y = MSD1, color = Treat))I hope this helps.?

Para: Bede-Fazekas ?kos; r-sig-ecology at r-project.org Dear ?kos Bede-Fazekas Sorry for the missed information. Please see the packages I used: library(readxl) library(dplyr) library(ggplot2) library(GGally) library(Hmisc) library(corrplot) library(PerformanceAnalytics) Then I import the attached dataset (Libro1) containing 5 variables: EMF, bio, MSD1, MSD2 (all of them numerical) and Treat (categorical).
Then I wrote:
chart.Correlation(Libro1, histogram = F, pch = 19)
And got the error: Error in pairs.default(x, gap = 0, lower.panel = panel.smooth, upper.panel = panel.cor) : non-numeric argument to 'pairs' And I would like to obtain the plot you can see on the doc file, where correlation points are divided by a category (red, gren and blue) Thanks a lot for your help Manuel -----Mensaje original----- De: R-sig-ecology <r-sig-ecology-bounces at r-project.org> En nombre de Bede-Fazekas ?kos Enviado el: domingo, 22 de marzo de 2020 16:57 Para: r-sig-ecology at r-project.org Asunto: Re: [R-sig-eco] correlation plot in color Dear Manuel, since neither a reproducible example or your dataset are provided, nor the details of your problem (results of sessionInfo(); the package of corrMatOrder(); the error message you got) are known by us, it is a bit hard to help you. Anyway, I guess, that your data is not in categorical (factor) but in ordinal (ordered) scale. If you convert your ordoered data to numeric with as.numeric(), then Spearman and Kendall rank correlations can be used.

Dear Drew, Thank you very much for your help. The thing is that when I import the dataset containing categorical and numeric variables and then I want to calculate the correlation graphic, Rstudio says that it is not posible as categorical variables can not be used for correlation. So, which is the code for calculating correlation plots including a categorical variable, which will be them used for adding colours depending of the levels of this categorical factor? Thanks a lot for your advise, I really apreciate your help.

I am working with a biological dataset (please see in attachment) composed by 5 variables. The columns EMF, Biodiversity, MDS1 and MDS2 are numerical variables whereas T is a categorical one. I would like to obtain a correlation chart showing correlation coefficients, histograms and different colours for each observation following the categorical variable "T". Please see below the initial chart I got but in which observations are not classified in different colours following the categorical variable "T". This is the code I used with any positive result back. corrMatOrder (dataset, histogram = T, pch = 19, method= spearman, family="CM Roman", col=c("red", "green3", "blue", "black")[code.levels(dataset$T)]) I work with Rstudio. Thank you very much for your time and help.
