Question

我正在尝试获取一个批处理文件来测试一个数字是否在两个数字之间，但它只检查第一个数字。我正在使用“和”运算符但它似乎不起作用。这是代码：

fail <- factor(c(2, 2, 2, 2, 1, 1, 1, 1, 1, 1, 2, 1, 2, 1,
                 1, 1, 1, 2, 1, 1, 1, 1, 1,2,2,2,2),
               levels = c(1, 2), labels = c("male", "female"))
gender <- factor(rep(c(1:9),3))

mypalette <- colorRampPalette(c("lightblue","darkblue"))
tbl <- spineplot(fail, gender, xlab="Gender", ylab="Income levels: 1 is lowest",
     xaxlabels=c("Male","Female"), col=mypalette(nlevels(gender)) )
print(tbl)

#        Income levels: 1 is lowest
# Gender   1 2 3 4 5 6 7 8 9
# male   2 1 2 1 3 2 2 2 1
# female 1 2 1 2 0 1 1 1 2

print.perc <- function(k, tbl, ndigits=2, str.pct="%") {
   # These lines of codes are the same used by from spineplot
   # for the calculation of the x-position of the stacked bars
   nx <- nrow(tbl)
   off <- 0.02
   xat <- c(0, cumsum(prop.table(margin.table(tbl, 1)) + off))
   posx <- (xat[1L:nx] + xat[2L:(nx + 1L)] - off)/2
   # Proportions by row (gender)       
   ptbl <- prop.table(tbl,1)
   # Define labels as strings with a given format
   lbl <- paste(format(round(100*ptbl[k,], ndigits), nsmall=ndigits), str.pct, sep="")
   # Print labels
   # cumsum(ptbl[k,])-ptbl[k,]/2 is the vector of y-positions
   # for the centers of each stacked bar
   text(posx[k], cumsum(ptbl[k,])-ptbl[k,]/2, lbl)
}

# Print income levels for males and females
strsPct <- c("%","%")
for (k in 1:nrow(tbl)) print.perc(k, tbl, ndigits=2, str.pct=strsPct[k])

Answer 1

逻辑and运营商不存在于BAT，

您必须针对您的变量进行第二次if测试：

else (if !total! gtr 4 if !total! leq 8 (....))

编辑：

 else (
     if !total! gtr 4 if !total! leq 8 (echo between 4 and 8)
     if !total! gtr 16 if !total! leq 32 (echo between 16 and 32)
     )

Answer 2

请参阅...链接IF命令（AND）。 https://ss64.com/nt/if.html

以下是Timo Salmi教授在IF声明中对AND / OR / XOR / NOT运算符的实现 http://www.netikka.net/tsneti/info/tscmd120.htm
