由上图可知,当第6个console.log(r.exec(s));没有匹配到,所以返回了null,lastIndex 也会重置为0,下一次调用时,又从头开始匹配了。 注意:如果在一个字符串中完成了一次模式匹配之后要开始检索新的字符串,就必须手动地把 lastIndex 属性重置为 0。 let s = "5aabcaba_a4aba_a a_a_abca_a a a_acbba...

xx<-1clusterExport(cl,"xx")clusterCall(cl,function(y)xx+y,2) 案例二:这个里面有xx这个变量是额外定义的,所以需要额外加载,需要用clusterExport函数,导入到并行环境中。 3、parallel内存优化与管理 (1)注意数据容量的均匀分布 代码语言:javascript
Relational mechanisms which are created on the basis of co-operation and dependent on agreed social-exchange norms function within dyadic inter-firm relationships (Wathne & Heide, 2004). Therefore, given that we have conducted this study only from the exporting seller’s perspective, we would ...

R语言相关的报错处理函数可见:R语言-处理异常值或报错的三个示例 用tryCatch跳过: result =tryCatch( {expr}, warning =function(w) {warning-handler-code}, error =function(e) { error-handler-code}, finally = {cleanup-code} ) 出现warning、error时候怎么处理,就可以跳过了。例子: ...
RNA binding of Ddx19 was disrupted by R371G (R369G in yeast) and R428Q (R426Q in yeast) mutations. Moreover, both of these mutants function as dominant negative in mRNA export18. We tested the functionality of the mutant constructs by measuring their ability to rescue the mRNA export ...
