On this R-data statistics page, you will find information about the plantTraits data set which pertains to Plant Species Traits Data. The plantTraits data set is found in the cluster R package. You can load the plantTraits data set in R by issuing the following command at the console data("plantTraits"). This will load the data into a variable called plantTraits. If R says the plantTraits data set is not found, you can try installing the package by issuing this command install.packages("cluster") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the plantTraits R data set. The size of this file is about 17,957 bytes. Plant Species Traits DataDescriptionThis dataset constitutes a description of 136 plant species according to biological attributes (morphological or reproductive) Usagedata(plantTraits) FormatA data frame with 136 observations on the following 31 variables.
DetailsMost of factor attributes are not disjunctive. For example, a plant can be usually pollinated by insects but sometimes self-pollination can occured.
