输入含DNA序列的矩阵或列表(List),类(Class)必须是DNAbin。若DNA序列被存储为字符(Character),可使用as.DNAbin函数来转换 dna.bin.dist = ape::dist.dna(ex.dna, model = "N", variance = FALSE, gamma = FALSE, pairwise.deletion = FALSE, base.freq = NULL, as.matrix = F) dna.bin.dist.sub ...
NULL经常被用作函数的一个参数,用来代表no value was assigned to the argument。有一些函数也可能返回NULL值。 强转规则(coercion) 下面是强转规则的概述 • Logical values are converted to numbers: TRUE is converted to 1 and FALSE to 0.
如果参数设置为auto.assign=FALSE或env=NULL,数据会从调用程序返回,且需要用户自己设定数据存储的位置。需要注意的是,这种情况下,每次仅允许一个symbol。 下载的symbols也会被储存在.getSymbols环境中。 参数设置为auto.assign=TRUE,此时下载的symbols对象可以使用showSymbols函数查看,removeSymbols函数删除。
