1d:T7a1,# Function for performing data.table operations on an object of class `treedata.table` This function can be used to subset rows, select and compute on columns data.table . ```r ## S3 method for class 'treedata.table' x[...] ``` ## Arguments - `x`: An object of class `treedata.table` - `...`: Arguments in the structure of `data.table` used to perform changes on the `treedata.table` object ## Returns A new object of class `treedata.table` with `$dat` and `$phy` corresponding with the changes set to `$dat` using data.table 's structure. ## Examples ```r data(anolis) anolis2 <- anolis$phy anolis2$tip.label[1] <- "NAA" anolis1 <- anolis$phy anolis1$tip.label[1] <- "NAA" trees <- list(anolis1, anolis2) class(trees) <- "multiPhylo" treesFM <- list(anolis$phy, anolis$phy) class(treesFM) <- "multiPhylo" # A phylo object that fully matches the data td <- as.treedata.table(tree = anolis$phy, data = anolis$dat) td <- as.treedata.table(anolis$phy, anolis$dat) td[, SVL] td[island == "Cuba" & ecomorph == "TG", .(ecomorph, island, SVL)] td[, utils::head(.SD, 1), by = .(ecomorph, island)] # A multiphylo object that fully matches the data td <- as.treedata.table(tree = treesFM, data = anolis$dat) td <- as.treedata.table(treesFM, anolis$dat) td[, SVL] td[island == "Cuba" & ecomorph == "TG", .(ecomorph, island, SVL)] td[, utils::head(.SD, 1), by = .(ecomorph, island)] # A phylo object that partially matches the data td <- as.treedata.table(tree = anolis1, data = anolis$dat) td <- as.treedata.table(anolis1, anolis$dat) td[, SVL] td[island == "Cuba" & ecomorph == "TG", .(ecomorph, island, SVL)] td[, utils::head(.SD, 1), by = .(ecomorph, island)] # A multiphylo object that partially matches the data td <- as.treedata.table(tree = trees, data = anolis$dat) td <- as.treedata.table(trees, anolis$dat) td[, SVL] td[island == "Cuba" & ecomorph == "TG", .(ecomorph, island, SVL)] td[, utils::head(.SD, 1), by = .(ecomorph, island)] ```1e:T49a,M7.49933 0.25C3.49635 0.25 0.25 3.49593 0.25 7.50024C0.25 10.703 2.32715 13.420
