ggadjustedcurves error: Must use a vector in '[', not an object of class matrix

Question

ggadjustedcurves 错误：必须在“[”中使用向量，而不是 class 矩阵的对象

我打电话给 rlang::last_trace() 得到这个：

> rlang::last_error()
<error>
message: Must use a vector in `[`, not an object of class matrix.
class:   `rlang_error`
backtrace:
  1. survminer::ggadjustedcurves(...)
  2. survminer:::ggadjustedcurves.average(data, fit, variable, size = size)
  4. base::sort.default(unique(data[, variable]))
  8. base::order(x, na.last = na.last, decreasing = decreasing)
  9. base::lapply(z, function(x) if (is.object(x)) as.vector(xtfrm(x)) else x)
 10. base:::FUN(X[[i]], ...)
 13. base::xtfrm.default(x)
 15. base::rank(x, ties.method = "min", na.last = "keep")
 17. tibble:::`[.tbl_df`(x, !nas)
 18. tibble:::check_names_df(i, x)

尝试使用分层变量绘制调整后的曲线。

Answer 1

我有一个非常相似的问题，但是当我为 post 生成样本数据集时，绘图起作用了，这让我觉得是我的数据出了问题。这是可重现的示例，其中两个图都很好地生成了。

# generate reproducible data set
set.seed(3)
sampleData <- data.frame(Has_an_A_allele = sample(c("Yes", "No"), 1000, replace = TRUE),
                         Survival = rexp(1000, 0.5),
                         Censored = as.numeric(sample(c("1", "0"), 1000, replace = TRUE)),
                         Disease = sample(c("A", "B"), 1000, replace = TRUE),
                         Gender = sample(c("Male", "Female"), 1000, replace = TRUE),
                         Stage = sample(c("Early", "Advanced"), 1000, replace = TRUE),
                         Age = sample(c("Under 60", "Over 60"), 1000, replace = TRUE))
Summary(sampleData)

# create survival fit
fit<-survfit(Surv(Survival, Censored) ~ Has_an_A_allele, data = sampleData)

# create survival plot with p value
ggsurvplot(fit5, sampleData, xlim = c(0, 10), break.time.by = 2, pval = TRUE)

# create faceted survival plot with p value
ggsurvplot(fit5, sampleData, xlim = c(0, 10), break.time.by = 2, facet.by = "Disease", pval = TRUE)

当我运行我的数据上的这段代码时，第一个图很好用，但是多面图 returns 这个错误

> ggsurvplot(fit4, x1502, xlim = c(0, 10), break.time.by = 2, facet.by = "Gender", pval = TRUE)
Error: Must use a vector in `[`, not an object of class matrix.
Call `rlang::last_error()` to see a backtrace
> rlang::last_error()
<error>
message: Must use a vector in `[`, not an object of class matrix.
class:   `rlang_error`
backtrace:
  1. survminer::ggsurvplot(...)
  4. survminer::surv_group_by(data, grouping.vars = facet.by)
  5. survminer:::.levels(data[, grouping.vars])
  6. base::as.factor(x)
  7. base::factor(x)
  8. base::order(y)
  9. base::lapply(z, function(x) if (is.object(x)) as.vector(xtfrm(x)) else x)
 10. base:::FUN(X[[i]], ...)
 13. base::xtfrm.default(x)
 15. base::rank(x, ties.method = "min", na.last = "keep")
 17. tibble:::`[.tbl_df`(x, !nas)
 18. tibble:::check_names_df(i, x)

示例数据中使用的列名与我的数据集中的列名相同，数据类型相同，即除了 Survival 和 Censored 之外的所有列都是因子。

编辑

我已经修复了它，确定这绝对是一个数据问题我查看了示例数据的结构和我的数据。

> str(x1502)
Classes ‘tbl_df’, ‘tbl’ and 'data.frame':   450 obs. of  7 variables:

> str(sampleData)
'data.frame':   1000 obs. of  7 variables:

所以我使用 x1502 <- as.data.frame(x1502) 将我的数据转换为数据框，现在一切正常。希望这对您的数据思维习惯有用。
