r - 我将 R“粒子”包应用于海洋速度数据并收到错误消息说我内存不足

Question

我正在尝试将 R“粒子”包中的示例应用于海洋速度数据（动能）。示例数据如下：

ke1<-c(0.394610137,0.203202814,0.12364389,0.069784589,0.048573241,0.043057494,0.03826768,0.034176417,0.032129359,0.03122394)
ke2<-c(0.094138406,0.169889584,0.086677499,0.070593894,0.049883354,0.042339094,0.038856283,0.037967827,0.036562074,0.037240546)
ke3<-c(0.054365572,0.096576959,0.10304369,0.061354585,0.053624138,0.042112421,0.040727202,0.039870735,0.042947762,0.043291345)
ke4<-c(0.030527802,0.075901449,0.08003746,0.068991989,0.048506431,0.044592839,0.04071483,0.042985249,0.042403288,0.044974718)
ke5<-c(0.021374704,0.047852065,0.070487022,0.059393879,0.051129311,0.042866949,0.040003292,0.040003441,0.044107087,0.04578279)
ke<-cbind(ke1,ke2,ke3,ke4,ke5)

library(particles)
library(tidygraph)
    

sim <- create_empty(1000) %>% 
  simulate(alpha_decay = 0, setup = aquarium_genesis(vel_max = 1)) %>%
  wield(reset_force, xvel = 0, yvel = 0) %>% 
  wield(field_force, angle = ke, vel = ke , xlim = c(-5, 5), ylim = c(-5, 5)) %>% 
      evolve(1000, record)

增加速度数据量(row = 233, col = 154)，出现如下错误。

Error: cannot allocate vector of size 152.6 Mb

我试图检查我用 gc() 使用的内存量。

 gc()
            used   (Mb) gc trigger   (Mb)  max used   (Mb)
Ncells   2765657   84.5    4718054  144.0   4718054  144.0
Vcells 311435640 2376.1  480298947 3664.4 439560179 3353.6

memory.limit 是 4000（上限）。我能说这是PC内存造成的吗？
