根据R'Memory-limits'文档,不可能分配长度大于2 ^ 31-1的向量.这是因为用作索引的整数只能使用31位(符号一位).但是在64位系统上,我应该能够分配更长的向量.为什么R在64位系统上施加相同的最大长度？有办法规避限制吗？
如何为r中的变量分配一个非常长的字符串？
以下工作正常
testVar <- "test;test;"
但是以下+在RStudio控制台中给出了一个奇怪的结果.
testVar <- "test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test
