在绘制数据时,“通过强制引入的NA”

2023年9月20日 257次阅读

我正在使用R中的晶格包在单个图形上绘制多个时间序列.每当我尝试这样做时,我都会收到错误消息“NA强制引入NA”.我认为问题是我在系列中缺少数据(即它们不是连续的,一些系列在以后的日期开始,等等).

特别：

1: In order(as.numeric(x)) : NAs introduced by coercion
2: In diff(as.numeric(x[ord])) : NAs introduced by coercion

这是我的代码：

library("lattice")
df1 <- structure(list(STRING = c("1A AUTO INC", "1A AUTO INC", "1A AUTO INC", 
"1A AUTO INC", "1A AUTO INC", "1A AUTO INC", "1A AUTO INC", "1A AUTO INC", 
"1A AUTO INC", "1A AUTO INC", "1A AUTO INC", "1A AUTO INC", "1A AUTO INC",

graph1 <- xyplot(ee_amt + elite_amt + Sabry_amt + depo_amt + tyc_amt ~ time, data = df1, type = "1", auto.key = TRUE)
print(graph1)

最佳答案 我建议这个错误的一部分是这个错误的事实是时间不是合适的时间甲酸盐,即

is.character(df1$time)

看到

df1$random<-1:length(df1[[1]])
graph1 <- xyplot(ee_amt + elite_amt + Sabry_amt + depo_amt + tyc_amt ~ random, data = df1, type = "l", auto.key = TRUE)

编辑：

或者@plannapus建议

df1$time <- as.Date(df1$time)
