让R缩写为用户提供的函数参数的字符输入

Question

背景：

我有一个名为abs的R函数。该函数只有一个名为main.name的参数。此函数的用户在引号中提供字符类型名称（例如，"Length of Residence"），函数abs使用此用户提供的名称作为简单图表的主标题。

问题

用户可以提供非常长的名称（例如，"Oral Language Ability of Minors"）。要克服这个问题：

我想知道当用户提供超过2个单词的 a main.name 时，R会选择每个单词的第一个字符并制作一个main.name的“缩写”？

例如，在这种像差之后，"Oral Language Ability of Minors"变为“OLAOM”。

abs = function (main.name) {

plot(rnorm(1e2), main = main.name)

} 

abs ("Oral Language Ability of Minors")
