R：SpatialPointsDataFrame 代码不再有效。 !res[[1]] 中的错误：参数类型无效

Question

我一直在关注 this workflow 在 R 中将坐标从 Eastings / Northings 转换为 Latitude / Longitude。直到今天它一直运行良好。这是一个可重现的例子：

require(rgdal)
# create test coordinates
x <- 259269 y <- 074728

# create test dataframe 
dat <- data.frame(x, y) 
class(dat) # "data.frame"

### shortcuts 
ukgrid <- "+init=epsg:27700" 
latlong <- "+init=epsg:4326"

### Create coordinates object 
coords <- cbind(Easting = as.numeric(as.character(x)),
                Northing = as.numeric(as.character(y)))
class(coords) # matrix
dat_SP <- SpatialPointsDataFrame(coords,
                              data = dat,
                              proj4string = CRS("+init=epsg:27700"))

# Error in !res[[1]] : invalid argument type

# Following steps ----

# Convert
dat_SP_LL <- spTransform(dat_SP, CRS(latlong)

# replace Lat, Long
dat_SP_LL@data$Long <- coordinates(dat_SP_LL)[, 1]
dat_SP_LL@data$Lat <- coordinates(dat_SP_LL)[, 2]

我认为这可能与proj4string参数有关，但一直无法解决。感谢任何帮助。

我遇到了同样的问题。它来自 CRS 函数。如果您查看它来自第 34 行的函数（我在下面的代码中用星号标记），但我不知道如何修复它。这可能是一个错误。我写这个"answer"主要是为了引起大家的注意，我没有资格评论

编辑：您可以在CRS函数中设置doCheckCRSArgs = F，但当我尝试spTransform时仍然出现错误。 source crs creation failed: generic error of unknown origin

function (projargs = NA_character_, doCheckCRSArgs = TRUE) 
{
  if (!is.na(projargs) && !nzchar(projargs)) 
    projargs <- NA_character_
  stopifnot(is.logical(doCheckCRSArgs))
  stopifnot(length(doCheckCRSArgs) == 1L)
  stopifnot(is.character(projargs))
  if (!is.na(projargs)) {
    if (length(grep("^[ ]*\+", projargs)) == 0) 
      stop(paste("PROJ4 argument-value pairs must begin with +:", 
        projargs))
  }
  if (!is.na(projargs)) {
    if (length(grep("latlon", projargs)) != 0) 
      stop("northings must follow eastings: ", projargs)
    if (length(grep("lonlat", projargs)) != 0) {
      projargs <- sub("lon", "long", projargs)
      warning("'lonlat' changed to 'longlat': ", projargs)
    }
  }
  if (is.na(projargs)) 
    uprojargs <- projargs
  else uprojargs <- paste(unique(unlist(strsplit(projargs, 
    " "))), collapse = " ")
  if (length(grep("= ", uprojargs)) != 0) 
    stop(paste("No spaces permitted in PROJ4 argument-value pairs:", 
      uprojargs))
  if (length(grep(" [:alnum:]", uprojargs)) != 0) 
    stop(paste("PROJ4 argument-value pairs must begin with +:", 
      uprojargs))
  if (doCheckCRSArgs) {
    if (!is.na(uprojargs) && requireNamespace("rgdal", quietly = TRUE)) {
      res <- rgdal::checkCRSArgs(uprojargs)
      ********if (!res[[1]])*********
        stop(res[[2]])
      uprojargs <- res[[2]]
    }
  }
  res <- new("CRS", projargs = uprojargs)
  res
}

我遇到了同样的问题。该错误与 sp::CRS 有关。我通过重新安装 'sp' 包解决了这个问题。
