我不相信dateInput已经实现了引导minViewMode选项作为函数参数，所以我在我自己的函数副本中添加了它（见下文）。我不得不添加一些其他必需的函数。这不是很好。最好的选择可能是向RStudio提交请求，因为添加这个minviewmode选项似乎很简单。

mydateInput <- function(inputId, label, value = NULL, min = NULL, max = NULL,
                      format = "yyyy-mm-dd", startview = "month", weekstart = 0, language = "en", minviewmode="months",
                      width = NULL) {
  
  # If value is a date object, convert it to a string with yyyy-mm-dd format
  # Same for min and max
  if (inherits(value, "Date"))  value <- format(value, "%Y-%m-%d")
  if (inherits(min,   "Date"))  min   <- format(min,   "%Y-%m-%d")
  if (inherits(max,   "Date"))  max   <- format(max,   "%Y-%m-%d")
  
  htmltools::attachDependencies(
    tags$div(id = inputId,
             class = "shiny-date-input form-group shiny-input-container",
             style = if (!is.null(width)) paste0("width: ", validateCssUnit(width), ";"),
             
             controlLabel(inputId, label),
             tags$input(type = "text",
                        # datepicker class necessary for dropdown to display correctly
                        class = "form-control datepicker",
                        `data-date-language` = language,
                        `data-date-weekstart` = weekstart,
                        `data-date-format` = format,
                        `data-date-start-view` = startview,
                        `data-date-min-view-mode` = minviewmode,
                        `data-min-date` = min,
                        `data-max-date` = max,
                        `data-initial-date` = value
             )
    ),
    datePickerDependency
  )
}

`%AND%` <- function(x, y) {
  if (identical(!is.null(x), !is.na(x)))
    if (identical(!is.null(y), !is.na(y)))
      return(y)
  return(NULL)
}

controlLabel <- function(controlName, label) {
  label %AND% tags$label(class = "control-label", `for` = controlName, label)
}

datePickerDependency <- htmlDependency(
  "bootstrap-datepicker", "1.0.2", c(href = "shared/datepicker"),
  script = "js/bootstrap-datepicker.min.js",
  stylesheet = "css/datepicker.css")

@MartinJohnHadley：基本上通过添加相同的三行@StevenMortimer添加到dateInput的代码到dateRangeInput。这将minViewMode添加到shinys dateRangeInput。
1.在https://github.com/rstudio/shiny/blob/master/R/input-daterange.R上找到代码
1.添加默认参数minviewmode="months"
1.将data-date-min-view-mode = minviewmode添加到两个div
1.添加缺少的参数（在github存档中搜索shiny）
1.享受您的自定义dateRange输入：-）

下面是另一个方法（代码冗余更少，希望更简单），由同事贡献。与复制shiny：：dateInput函数代码不同，可以在之后将min/max-view-mode部分添加到Shiny对象中。然后可以按预期使用旧参数'startview'和新的'minview'/'maxview'：

dateInput2 <- function(inputId, label, minview = "days", maxview = "decades", ...) {
  d <- shiny::dateInput(inputId, label, ...)
  d$children[[2L]]$attribs[["data-date-min-view-mode"]] <- minview
  d$children[[2L]]$attribs[["data-date-max-view-mode"]] <- maxview
  d
}

dateRangeInput2 <- function(inputId, label, minview = "days", maxview = "decades", ...) {
  d <- shiny::dateRangeInput(inputId, label, ...)
  d$children[[2L]]$children[[1]]$attribs[["data-date-min-view-mode"]] <- minview
  d$children[[2L]]$children[[3]]$attribs[["data-date-min-view-mode"]] <- minview
  d$children[[2L]]$children[[1]]$attribs[["data-date-max-view-mode"]] <- maxview
  d$children[[2L]]$children[[3]]$attribs[["data-date-max-view-mode"]] <- maxview
  d
}

下面是一个简单的例子：

library(shiny)
shinyApp(
  ui = fluidPage(
    dateInput2("test1", "Year", startview = "year", minview = "months", maxview = "decades"),
    dateRangeInput2("test2", "Years", startview = "year", minview = "months", maxview = "decades")
  ),
  server = function(input, output, session) {}
)

更新：

为了解决下面darKnight的问题，我扩展了这个例子，并引入了一个参数来设置最大可选时间分辨率。有关可能参数的完整列表，请参阅：
https://bootstrap-datepicker.readthedocs.io/en/latest/options.html

想使用上一个答案中的代码的人：您需要使用更新的datePickerDependecy（可以从https://github.com/rstudio/shiny/blob/master/R/input-date.R获取）。
目前它是：

datePickerDependency <- htmlDependency(
"bootstrap-datepicker", "1.6.4", c(href = "shared/datepicker"),
script = "js/bootstrap-datepicker.min.js",
stylesheet = "css/bootstrap-datepicker3.min.css",
# Need to enable noConflict mode. See #1346.
head = "<script>
(function() {
var datepicker = $.fn.datepicker.noConflict();
$.fn.bsDatepicker = datepicker;
})();
</script>")
