我试图找到以下参数的交集：
ma.20 <- SMA(x[,5], 20)
ma.50 <- SMA(x[,5], 50)
price.b <- ifelse(sign(x[,5])- runMax(x[,1], 20) | sign(runMin(x[,2],20)-x[,5])==1, 1, 0)
ma.break <- sign(x[,5]-ma.50)
rev.ma <- sign(ma.50-ma.20)
sig <- union(which(!p.break[1,]==0), which(!ma.break[1,]==0), which(!rev.ma<0)) ## Retrieves signals
}
基本上，如果其中一个参数成立，我试图检索列号:( p.break [，1] == 0或ma.break [1，] == 0或rev.ma [ 1，] == 0），但上面的命令返回：
Error in base::union(x, y, ...) :
unused argument (c(66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223))
我非常感谢一些建议。我使用TTR包来计算SMA。附件是我的意思：
