We can also subset on numeric columns. If we wanted to see rows where payments equal $100, you would do the following: subset(debt, payment == 100) Powered By name payment 1 Dan 100 6 Rob 100 Powered By Accessing and Subsetting Dataframes Moving to this next example, what if ...
{find all values that are false}]${all those columns} <- '0' ## df3 should match this: df3 <- data.frame(a = '-1', b = '0', c = '0', d = '-1', e

R语言CMplot包绘制曼哈顿图 曼哈顿图本质上是一个散点图,用于显示大量非零大范围波动数值,最早应用于全基因组关联分析(GWAS)研究展示高度相关位点。它得名源于样式与曼哈顿天际线相似。 近几年,在宏基因组领域,尤其是差异OTU结合分类学结果,采用Manhattan plot展示有非常好的效果,倍受推崇。 曼哈顿图优点 大数据中,即...
