[問題類型]: 程式諮詢(我想用R 做某件事情，但是我不知道要怎麼用R 寫出來) [軟體熟悉度]: 入門(寫過其他程式，只是對語法不熟悉) [問題敘述] : 之前曾經用 quantmod package 抓過台灣個股的資料開發 shiny，但在近期發現套件沒辦法到 Yahoo Finance 抓台灣個股資料了，有上網查過問題，問題似乎來自 Yahoo Finance API 的網址有更動，但網路好像沒有解決方法（如下文），但若直接到 Yahoo Finance 的 Historical Data 區似乎還是可以下載 csv 檔，不確定是否可以 debug，或有其他方法可以用 R 抓個股股價資料？感激不盡（已跪）根據此文： https://github.com/joshuaulrich/quantmod/issues/149 [程式範例]: > library(quantmod) > getSymbols('2330.TW') Error in download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m, : 無法開啟 URL 'https://ichart.finance.yahoo.com/table.csv?s=2330.TW&a=0&b=01& c=2007&d=6&e=08&f=2017&g=d&q=q&y=0&z=2330.TW&x=.csv' 此外: Warning message: In download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m, : URL 'https://ichart.finance.yahoo.com/table.csv?s=2330.TW&a=0&b=01&c= 2007&d=6&e=08&f=2017&g=d&q=q&y=0&z=2330.TW&x=.csv': status was 'Couldn't resolve host name' [環境敘述]: > sessionInfo() R version 3.4.0 (2017-04-21) Platform: x86_64-apple-darwin15.6.0 (64-bit) Running under: OS X El Capitan 10.11.6 Matrix products: default BLAS: /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib LAPACK: /Library/Frameworks/R.framework/Versions/3.4/Resources/lib/libRlapack.dylib locale: [1] zh_TW.UTF-8/zh_TW.UTF-8/zh_TW.UTF-8/C/zh_TW.UTF-8/zh_TW.UTF-8 attached base packages: [1] stats graphics grDevices utils [5] datasets methods base other attached packages: [1] gridExtra_2.2.1 urca_1.3-0 [3] quantmod_0.4-10 TTR_0.23-1 [5] xts_0.9-7 zoo_1.8-0 [7] plotly_4.7.0 ggplot2_2.2.1 [9] shiny_1.0.3 loaded via a namespace (and not attached): [1] Rcpp_0.12.11 magrittr_1.5 [3] munsell_0.4.3 lattice_0.20-35 [5] viridisLite_0.2.0 colorspace_1.3-2 [7] xtable_1.8-2 R6_2.2.2 [9] httr_1.2.1 plyr_1.8.4 [11] dplyr_0.7.1 tools_3.4.0 [13] grid_3.4.0 nlme_3.1-131 [15] gtable_0.2.0 DBI_0.7 [17] htmltools_0.3.6 yaml_2.1.14 [19] lazyeval_0.2.0 digest_0.6.12 [21] assertthat_0.2.0 tibble_1.3.3 [23] tidyr_0.6.3 purrr_0.2.2.2 [25] htmlwidgets_0.8 mime_0.5 [27] compiler_3.4.0 scales_0.4.1 [29] jsonlite_1.5 httpuv_1.3.5 [關鍵字]: quantmod -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 101.14.51.78 ※ 文章網址: https://www.ptt.cc/bbs/R_Language/M.1499501265.A.2AE.html
