Getting the temperature by pixel in MODIS in rgee package

[eeedasc]

• rgee version: 1.1.5
• R version: 4.2.1
• Operating System: Windows 10

At submit an issue, please attached the following information of your rgee session:

• [ ] You have the Python API installed (from terminal):

  earthengine -h

• [ ] You can find the credentials file on your system:

  library(rgee)
  ee_path <- path.expand("~/.config/earthengine/credentials")
  file.exists(ee_path)

• [ ] You can run a simple EE command from R:

library(rgee)

# Initialize the Earth Engine module.
ee_Initialize()

# Print metadata for a MODIS dataset.
print(ee$ImageCollection("MODIS/061/MOD11A2")$getInfo())

Attach your Python (reticulate) configuration:

library(reticulate)
py_config()

Description

I want to extract the temperature values by pixel in MODIS data using rgee package. I have the polygon about the project in the featureCollection type.

What I Did

shp = ee$FeatureCollection('users/zeycasozen/R_LST');
print(shp);

ckale_img = ee$ImageCollection("MODIS/061/MOD11A2")$filter(ee$Filter$date('2003-01-01', '2003-02-01'));

library(rgee)
library(tidyverse)
ee_Initialize()

# Getting temperature band from Landsat 8
start <- ee$Date$fromYMD(2003,1,1) # Start date for filtering
end <- ee$Date$fromYMD(2003,2,1)  # End date for filtering

imgC <- ee$ImageCollection("MODIS/061/MOD11A2")$filterDate(start,end) 
  # ee$ImageCollection$map(qFn) 

mod <- imgC$select("LST_Day_1km") %>%   # Selecting temperature parameters
  ee$ImageCollection$median() %>% # Getting image by taking median
  ee$Image$clip(shp)             # Clipping image to city boundaries

# Calculating mean of cities - tempMean feature collection does not contain a mean property
data_city <- ee_extract(
  x = mod,
  y = shp,
  sf = TRUE,
  fun = ee$Reducer$median(),
  scale = 1000
)

**Number of features: 1 (result = created single values )

OR 

getRegion <- ckale_img$getRegion(geometry = shp,
                                 scale = 1000)
print(getRegion$getInfo())

...

But I want extract values from each pixel in MODIS data. How can I do? Thank you.
