r - how to find the list of different geoms and aesthetics -

-

this question has answer here:

i trying find list of aesthetics , geoms in ggplot2 package r , problem help(qplot) not yield results. can not find way invoke aesthetics or geoms.

what correct way invoke aesthetics in r?

the best approach can think of @ help(aes) gives links to

help(aes_colour_fill_alpha) help(aes_group_order) help(aes_linetype_size_shape) help(aes_position)

which summarize various aes sub groups.

you 1 of these if search particular aestheic (eg help(alpha) or help(group)

for list of geoms, @ index help, under g. perhaps when documentation layer completed (or started) spur similar listing / sub grouping.

you extract relevant exported objects within ggplot2 namespace using

ls(pattern = '^geom_', env = as.environment('package:ggplot2'))   ## [1] "geom_abline"     "geom_area"       "geom_bar"        "geom_bin2d"      "geom_blank"      "geom_boxplot"    "geom_contour"     ## [8] "geom_crossbar"   "geom_density"    "geom_density2d"  "geom_dotplot"    "geom_errorbar"   "geom_errorbarh"  "geom_freqpoly"   ## [15] "geom_hex"        "geom_histogram"  "geom_hline"      "geom_jitter"     "geom_line"       "geom_linerange"  "geom_map"        ## [22] "geom_path"       "geom_point"      "geom_pointrange" "geom_polygon"    "geom_quantile"   "geom_raster"     "geom_rect"       ## [29] "geom_ribbon"     "geom_rug"        "geom_segment"    "geom_smooth"     "geom_step"       "geom_text"       "geom_tile"       ## [36] "geom_violin"     "geom_vline"

ggplot2 has unexported character vector .all_aesthetics contains possible aesthetics

ggplot2:::.all_aesthetics

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
