在以下代码的末尾,我想打印n_species
,但我首先要打印"物种的数量是"然后是价值。我怎么能这样做?
n_species <- 0
n_invisibility <- 0
for(i in Species) {
n_species <- n_species + 1
for(i in Invisibility){
if(i == "Y") {
n_invisibility <- n_invisibility + 1
}
else {
n_invisibility <- n_invisibility + 0
}
}
}
print(n_species)
print(n_invisibility)
答案 0 :(得分:2)
另一个允许轻松控制数字格式的选项:
sprintf("The number of species is %i.", n_species)
答案 1 :(得分:1)
print(paste("The number of species is",n_species))
粘贴也会获取参数sep,其中默认值为sep=" "
,并且如果您尝试将其作为字符串打印(以及更多),则折叠基本上是矢量分离。
