gtrendsR查詢問題

我在gTrendsR搜索中收到兩個錯誤。我試圖將這個軟件包與來自https://github.com/PMassicotte/gtrendsR的CRAN下載和devel版本一起使用。gtrendsR查詢問題

library(gtrendsR) 
gconnect(usr, psw, verbose=TRUE) 
#Google login successful! 
sport_trend <- gtrends(c("nhl", "nba", "nfl")) 
#Error in names(trend) <- make.names(paste(kw, geo)) : 
# 'names' attribute [3] must be the same length as the vector [0] 

gtrends("Kim Kardashian") 
#Error: Not enough search volume. Please change your search terms.

我已經嘗試了很多搜索條件無濟於事。有問題的功能似乎是.processResults：

kw <- trimws(unlist(strsplit(queryparams[1], ","), use.names = FALSE)) 
    geo <- trimws(unlist(strsplit(queryparams[3], ","), use.names = FALSE)) 
    names(trend) <- make.names(paste(kw, geo))

這些表述似乎沒有依靠搜索結果，但在查詢本身。第二個錯誤源於：

if (length(vec) < 2) { 
    stop("Not enough search volume. Please change your search terms.", 
     call. = FALSE) 
    }

變量vec從getForm我無法找到文件獲取其值。我試圖指定查詢項目，但也沒有工作。重新啓動R會話也沒有解決問題。

有趣。我無法使用R版本3.2.2（2015-08-14），平臺：x86_64-w64-mingw32/x64（64位），運行於：Windows 7 x64（內部版本7601）Service Pack 1，gtrendsR_1下重現錯誤。 3.1（...） – lukeA

我有同樣的問題。出於某種原因，改變我的代碼如下所示。希望你能弄清楚爲什麼。我是小白。

> styles <- gtrends(query=c("Pixie Pant", "Yoga Pants", "Jeans")) 
# Error in names(trend) <- make.names(paste(kw, geo)) : 
# 'names' attribute [3] must be the same length as the vector [2] 
> commodities2 <- gtrends(c("Oil prices", "mortgage rates"), res="7d", geo= "US") 
> styles <- gtrends(c("Pixie Pant", "Yoga Pants", "Jeans")) 
# Error in names(trend) <- make.names(paste(kw, geo)) : 
# 'names' attribute [3] must be the same length as the vector [2] 
> styles <- gtrends(c("Pixie Pant", "Yoga Pants", "Jeans"), res="7d", geo= "US") 
> plot(styles)

由於Google API更改，程序包作者不得不進行完全重寫。獲取未發佈的gtrendsR 2.0.0代碼：

devtools::install_github('PMassicotte/gtrendsR') 

library(gtrendsR) 
# do not need to log in anymore 
# syntax change! 
gt.us <- gtrends("USA", geo="US", time = "2004-01-01 2004-01-30")
