我正试图将以下内容设置为数据帧，并通过0.05将参数d从0.05更改为0.5。我最感兴趣的值是s1_limiting_ratio。我对R还很陌生，所以设置数据帧对我来说仍然有点困惑。
r <- 0.7
g1 <- 0.00000000175
g2 <- 0.000000296
v1 <- 0.000000296
v2 <- 0.000000296
k1 <- 2.8
k2 <- 7.7
s01 <- 1
s02 <- 400
d <- 0.05
s1_star <- (r*g1*k1*d)-((v1*(r-d))-r*g1*d)
s2_star <- (r*g2*k2*d)-((v2*(r-d))-r*g2*d)
s1_limiting_equation <- s1_star+((s02-s2_star)*(g1/g2))
s1_limiting_ratio <- s02/s1_limiting_equation
谢谢！
r <- 0.7
g1 <- 0.00000000175
g2 <- 0.000000296
v1 <- 0.000000296
v2 <- 0.000000296
k1 <- 2.8
k2 <- 7.7
s01 <- 1
s02 <- 400
df <- data.frame(d = seq(0.05, .5, 0.05)) %>%
mutate(
s1_star = (r*g1*k1*d)-((v1*(r-d))-r*g1*d),
s2_star = (r*g2*k2*d)-((v2*(r-d))-r*g2*d),
s1_limiting_equation = s1_star+((s02-s2_star)*(g1/g2)),
s1_limiting_ratio = s02/s1_limiting_equation
)
输出：
