本文介绍了如果功能在R的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我在R中很新。我有两组数据。 当差值超过某个阈值时,我将它们标记为异常值。 现在,我想创建一个函数,从Table_2中减去Table_1列的行,其中标签是Result列中的outlier。 errorr errorr< - transform(errorr,Result = ifelse(Table_1 -0.3< Table_2& Table_2< Table_1 + 0.3,'Normal','Outlier')) $ b 示例数据: Table_1 Table_2结果 1 5.778986 5.58正常 2 5.768515 6.50异常值 3 5.758068 5.83正常 4 5.747644 5.54正常 5 5.737245 5.80正常 6 5.726869 6.03异常值 预期结果: 5.768515 - 6.50 = -0.731485 5.726869 - 6.03 = -0.303131 解决方案另外,也许(虽然输出不那么漂亮) diff(t(dat [dat $ result ==Outlier,2:1])) ## 2 6 ## Table_1 -0.731485 -0.303131 I am quite new in R. I have two set of data.I have labeled them as "outlier" when the difference exceeds a certain threshold.Now, I would like to make a function which subtract the row of Table_1 column from Table_2 where label is "outlier" in the Result column.Code:errorr <- data.frame(Table_1=unname(x.fore$pred), Table_2=unname(rn25_29_t$ambtemp))errorr <- transform(errorr, Result = ifelse(Table_1 - 0.3 < Table_2 & Table_2 < Table_1 + 0.3, 'Normal', 'Outlier'))Sample data: Table_1 Table_2 Result1 5.778986 5.58 Normal2 5.768515 6.50 Outlier3 5.758068 5.83 Normal4 5.747644 5.54 Normal5 5.737245 5.80 Normal6 5.726869 6.03 OutlierExpected result:5.768515 - 6.50 = -0.7314855.726869 - 6.03 = -0.303131 解决方案 Also, maybe (although the output is less pretty)diff(t(dat[dat$Result == "Outlier", 2:1]))## 2 6## Table_1 -0.731485 -0.303131 这篇关于如果功能在R的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 09-26 14:51
