R语言代码块如何高亮显示

本篇内容主要讲解"R语言代码块如何高亮显示"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"R语言代码块如何高亮显示"吧!

Tips：

1.代码中的注释行应该单独一行，前后各空一行，以免造成代码高亮显示错误；

2.在代码中已经添加代码高亮后，代码需要空行时可用 shift+enter键添加空行，而直接enter代码块会断裂；

如下是空行后，完美显示：

use Bio::SeqIO;use Bio::Seq;use Data::Dumper;$in  = Bio::SeqIO->new(-file => "D:/share/scripts/Arabidopsis_thaliana.TAIR10.cds.all.fa" ,                               -alphabet=>"dna",                               -format => 'Fasta');$out = Bio::SeqIO->new(-file => ">D:/share/scripts/aa.fa" ,                               -format => 'fasta');while ( my $seqobj = $in->next_seq() ) {# the human read-able id of the sequencemy $id=$seqobj->id();  # string of sequencemy $seq=$seqobj->seq();# a description of the sequencemy $desc=$seqobj->desc(); # one of 'dna','rna','protein'  https://www.bioinformatics.org/sms/iupac.htmlmy $alphabet=$seqobj->alphabet(); my $len=$seqobj->length();print $id."\n";print $seq."\n";print $desc."\n";print $alphabet."\n";print $len."\n";print $seqobj."\n";print Dumper($seqobj);$out->write_seq($seqobj);last;}

如果没有空行，代码显示会有错误：

use Bio::SeqIO;use Bio::Seq;use Data::Dumper;$in  = Bio::SeqIO->new(-file => "D:/share/scripts/Arabidopsis_thaliana.TAIR10.cds.all.fa" ,                               -alphabet=>"dna",                               -format => 'Fasta');$out = Bio::SeqIO->new(-file => ">D:/share/scripts/aa.fa" ,                               -format => 'fasta');while ( my $seqobj = $in->next_seq() ) {# the human read-able id of the sequencemy $id=$seqobj->id();  # string of sequencemy $seq=$seqobj->seq();# a description of the sequencemy $desc=$seqobj->desc(); # one of 'dna','rna','protein'  https://www.bioinformatics.org/sms/iupac.htmlmy $alphabet=$seqobj->alphabet(); my $len=$seqobj->length();print $id."\n";print $seq."\n";print $desc."\n";print $alphabet."\n";print $len."\n";print $seqobj."\n";print Dumper($seqobj);$out->write_seq($seqobj);last;}
