else if (non.numeric) { for (j in pseq) { # 如果是字符串,不转换 if (is.character(X[[j]])) next # 如果是逻辑值,调用as.character else if (is.logical(xj <- X[[j]])) xj <- as.character(xj) else { # 如果有NA,先确定位置 miss <- (xj) # 如果是因子,调用as.vector,否则调...
defaultPxRegStr = 'R:000 G:000 B:000' There are two steps to get the pixel region string for the specified pixel in the same string format. First, get a functionformatFcnthat formats numeric pixel values by using thegetPixelRegionFormatFcnfunction. Then, specify the row and column coordin...

If there is a numeric type, and we cast it into a string, then it should be numeric&string or at least string but not int as in the next example. Code snippet that reproduces the problem https://phpstan.org/r/d13c93de-adae-4900-a9b9-b9331c13e992 Expected output no error Member ...
Recently, the Lyndon factorization has been proved to preserve common factors in overlapping reads [6], thus leading to the idea of using factorizations of sequences to define measures of similarity between reads. In this paper we propose as a signature of sequencing reads the notion of ...
