R 从多个单独变量创建一个合并变量
任何帮助都将不胜感激 我有一个从PCR板软件导出的文件。我已经对所有等位基因进行了编码，现在将它们合并到一个数据帧中 我需要创建一个新的变量，合并3个等位基因（G1-1、G1-2和G2），以获得最终的基因型 然后我需要计算等位基因的发生率，以生成我需要生成的其他3个APOL1风险变量R 从多个单独变量创建一个合并变量,r,dataframe,recode,categorization,R,Dataframe,Recode,Categorization,任何帮助都将不胜感激 我有一个从PCR板软件导出的文件。我已经对所有等位基因进行了编码，现在将它们合并到一个数据帧中 我需要创建一个新的变量，合并3个等位基因（G1-1、G1-2和G2），以获得最终的基因型 然后我需要计算等位基因的发生率，以生成我需要生成的其他3个APOL1风险变量 Allele logic for final genotype: +/G2 = (G1-1-1(+) & G1-1-2(+)) & (G1-2-1(+) & G1-2-2(+)) &am
