df dataset

Data frame for package MicroNiche

This data frame consists of taxa (rows) by samples (columns). Taxa are separated into six distributions (D1 - 6) with 10 'species' per distribution. Samples are separated into four 'environments' (R1 - 4) with 10 samples per environment. data

data("df")

A data frame with 60 observations on the following 41 variables.

• Taxon: a factor with levels D1S1 D1S10 D1S2 D1S3 D1S4 D1S5 D1S6 D1S7 D1S8 D1S9 D2S1 D2S10 D2S2 D2S3 D2S4 D2S5 D2S6 D2S7 D2S8 D2S9 D3S1 D3S10 D3S2 D3S3 D3S4 D3S5 D3S6 D3S7 D3S8 D3S9 D4S1 D4S10 D4S2 D4S3 D4S4 D4S5 D4S6 D4S7 D4S8 D4S9 D5S1 D5S10 D5S2 D5S3 D5S4 D5S5 D5S6 D5S7 D5S8 D5S9 D6S1 D6S10 D6S2 D6S3 D6S4 D6S5 D6S6 D6S7 D6S8 D6S9

Details

An object of class "data.frame" of 60 rows x 40 columns, representing taxa and samples, respectively.

Source

Generated in silico to compare taxa of known distributions: D1 are generalists roughly in equal abundance across the four environments. D2 decrease linearly across the four environments. D3 are specialists that decrease exponentially across the four environments. D4 are specialists unique to one of the four environments. D5 are specialists in environments two and four, with no relationship with an environmental gradient supplied in the vignette. Finally, D6 represent low, spurious counts haphazardly distributed across all samples often present in microbial count tables.
