A list of puns related to "Centroid"
I'm trying to convert a csv file set of values into a raster but keep receiving the above error.
#Set raster options to improve speed of calculation
rasterOptions(tmptime = 4,
progress = "text", #displays raster operation progress bar
timer = TRUE, #outputs raster calculation duration
maxmemory = 10e+9, #max no. of bytes to read into memory
chunksize = 5e+9, #max no. of bytes to read/write in a single chunk while processing disk-based raster objects
tmpdir = tmp_path) #location for writing temporary file
#Define CRS
WGS84 <- "+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0"
#select csv file containing RR predicted poverty
pov_csv_path <- "" #paste CSV Flile
#set csv path's parent directory as working directory
setwd(dirname(dirname(pov_csv_path)))
#load csv to dataframe
df_pov<- read.csv(pov_csv_path)
#Subset the predicted poverty dataframe to get the grid ID & lat and lon
centroids <- df_pov %>%
select(id,lon,lat)
#Make a raster from centroids
#Function generates raster from regular grids like dataset used - assumes minimum distance between x & y coordinates is raster resolution
centroid_rast <- rasterFromXYZ(xyz = centroids[,c("lon","lat","id")], crs=WGS84)

Doing some Big Data coursework for my DS Masters and I am pretty confused by what I'm seeing. I'm running k-means clustering on Mahout and understand you can generally get different final centroids in k-means because it initializes them randomly... But I've initialized clusters using canopy clustering and even after that am seeing wide variance in the final density values. Here's one example:
Run | Inter-cluster density | Intra-cluster density |
---|---|---|
1 | 0.430836339 | 0.590516787 |
2 | 0.618821774170647 | 0.581433137 |
3 | 0.4960634 | 0.567159394 |
I've run this for different k values, distance metrics and max iteration values. The behavior is similar.
This is problematic because the purpose of this project is to compare performance across different parameter values. With such divergent results within the same parameter set, I'm forced to run each set of parameters multiple times and take an average, which is drastically increasing processing time and computation cost.
Is this expected behavior? Did I misunderstand something?
Im trying to get the centroid of the parabola with the vertex, but I do not know which of these formulas to follow.

Not finding a lot of information on a Centroid Acorn being used to control a plasma table but that is the path I would like to go down for my build. Any recommendations for a good thc that plays well with the acorn? Any other pitfalls to watch out for when using an acorn on a plasma table?
Hello everyone,
is there a possibility to measure the distance between the cell centroid and boundary face centroid d_1 and d_2 of specific cells in STAR-CCM+?

Hello everyone, I just had a quick question I was hoping someone could help me with. I have a shapefile of boundaries of Texas census blocks and I need to get the centroids of each of these census blocks, but I am unsure how I would be able to do that. I have tried using the mean center tool, but only some of the census blocks show up after using this tool. If anyone would be able to help with this at all, it would be greatly appreciated!
I got a geo fraction and a foreachloop to put each piece on it's centroid, and want the pieces to move away from the original geo in a pulse-like style, only moving directly away from where it was if that makes sense. I've tried different ways and just haven't found the solution to it.
I feel like it is a simple line of code involving the Normals of specific faces but can't quite figure out what that is. Any help would be appreciated!
Can put a link of the file if needed.

Hello all,
Is it possible to find the maximum weight or force that can be applied to the center of a beam of a given length with the following provided specs? How?
- dimensions: 15x15mm width and height
- weight: 0,297 gram per mm
- material: aluminum , v2.1 6063-T5
- stiffness area: 113,52mmΒ²
- polar moment of inertia of the area, at the centroid = 4705,05mmβ΄
- principal moments of inertia of the area, at the centroid:
lx = 2352,52mmβ΄
ly = 2352,52mmβ΄
The beams in question are openbeam / makerbeamxl.
