java找不到对象异常_找不到对象错误

我似乎真的找到一个能帮我解决我遇到的实际问题的人 .

这是我的代码&＃xff1a;

library(RNeo4j)

library(tidyverse)

library(stringr)

library(MASS)

### uncomment the next 2 lines to reconnect to server & re-query the database

# setwd("~/Desktop/Dashrock/Neo4j")

# source("N4j_connect_query.R")

df %

group_by(m.mkt,c1.name) %>%

summarize(n1_4_pct &＃61;sum(n.n1_4)/sum(n.est),

n5_9_pct &＃61;sum(n.n5_9)/sum(n.est),

n10_19_pct &＃61;sum(n.n10_19)/sum(n.est),

n20_49_pct &＃61;sum(n.n20_49)/sum(n.est),

n50_99_pct &＃61;sum(n.n50_99)/sum(n.est),

n100_249_pct &＃61;sum(n.n100_249)/sum(n.est),

n250_499_pct &＃61;sum(n.n250_499)/sum(n.est),

n500_999_pct &＃61;sum(n.n500_999)/sum(n.est),

n1000_pct &＃61;sum(n.n1000)/sum(n.est),

n1000_1_pct &＃61;sum(n.n1000_1)/sum(n.est),

n1000_2_pct &＃61;sum(n.n1000_2)/sum(n.est),

n1000_3_pct &＃61;sum(n.n1000_3)/sum(n.est),

n1000_4_pct &＃61;sum(n.n1000_4)/sum(n.est),

ap &＃61; sum(n.ap),

emp &＃61; sum(n.emp),

num_firms &＃61; sum(n.est))

g

g &＃43;

geom_point(aes(x&＃61;c1.name, y&＃61;n100_249_pct, color &＃61; factor(m.mkt)), na.rm &＃61; TRUE) &＃43;

facet_grid(. ~ m.mkt) &＃43;

labs(x &＃61; "Industry Code (NAICS)", y &＃61; "Btwn 100-249 Employees (as % of All Companies)", title &＃61; "Company Profiles") &＃43;

theme(axis.text.x &＃61; element_text(angle&＃61;90, hjust &＃61; .5, vjust&＃61;.5, size&＃61;5))

这很好用 . 这是输出&＃xff1a;

问题是&＃xff0c;当我从 geom_point 更改为 geom_bar (这是我真正想要的)时&＃xff0c;我得到了此错误的不同版本&＃xff1a;

因子(n100_249_pct)出错&＃xff1a;找不到对象&＃39;n100_249_pct&＃39;

怎么了&＃xff1f;
