fread 中的错误（showProgress 不是类型整数而是类型 'logical'。请报告。）

Question

我用过fread读取数据。但是错误出现了：

showProgress is not type integer but type 'logical'. Please report.

这是可重现的脚本：

library(data.table)
x <- "sgsddsfsfsf"
write.csv2(x,"check.csv", row.names=FALSE)
fread("check.csv", stringsAsFactor=FALSE)

打印屏幕示例：

刚刚修复。请从开发人员重试。感谢报告。

Fixed fread() error occurring for a subset of Windows users: showProgress is not type integer but type logical, #1944 and #1111. Our tests cover this usage (it is just default usage), pass on AppVeyor (Windows), win-builder (Windows) and CRAN's Windows so perhaps it only occurs on a specific and different version of Windows to all those. Thanks to @demydd for reporting. Fixed by using strictly logical type at R level and Rboolean at C level, consistently throughout.
