geom_bar() 빈 줄을 제공합니다

Question

ggplot2 패키지의 geom_bar() 기능에 문제가 있습니다. 나는 아이디어가 없다 왜 내가 빈 줄거리를 얻을! Variable == 'DDIFF_IK' 인 데이터 집합을 필터링 할 때 플롯이 그려지지 않으며 다른 어떤 Variable도 잘 작동합니다. 나는 누군가가 저에게 정보가 잘못된 점을 알려주기를 바랍니다. 여기

는 Variable == 'DDIFF_IK'에 대한 샘플 데이터입니다 :

Answer 1

문제는 크기가 아니라 앞에서 설명한 것처럼 데이터에 data$Value_y[6]과 data$Value_y[5]이 모두 -0.15라는 사실입니다. 이로 인해 중복이 발생합니다.
호기심에 data$Value_y[6]==data$Value_y[5]은 FALSE을 반환하므로 length(unique(data$Value_y)을 nrow(data)으로 비교했을 때 나는 그것을 잡지 않았습니다.
그러나 data=data[-6,] 또는 data=data[-5,] 중 하나를 제거하면 플롯이 그려집니다.
