R代码错误-“参数暗示行数不同”

Question

我遇到了错误：插入返回代码时，参数暗示行数不同。

gdf_Google_Close <- data.frame(Date = as.Date(cta5Data$ï..Date, format="%m/%d/%Y"), 
                                Close = cta5Data$Google.Close)
gdf_Amazon_Close <- data.frame(Date = as.Date(cta5Data$ï..Date, format="%m/%d/%Y"), 
                               Close = cta5Data$Amazon.Close)
base_Close <- ggplot(gdf_Google_Close,aes(Date,Close)) +
                  geom_line(aes(color="Google")) +
                  geom_line(data=gdf_Amazon_Close, aes(color="Amazon")) +
                  labs(color="Close")

gdf_Google_Return <- data.frame(Date = as.Date(cta5Data$ï..Date, format="%m/%d/%Y"), 
                                Return = cta5Data$Google.Return)

Error in data.frame(Date = as.Date(cta5Data$ï..Date, format = "%m/%d/%Y"),  : 
  arguments imply differing number of rows: 253, 0
